        Option Response problems present foils to the student with drop-down boxes. The student can select the matching choice for the foils from a list of choices. Optionally, the foils may be bundled into Concept Groups and the system will select one foil from each group to display to the student.
        
        By default, the list of options is presented in front of the foils. Using the optional drawoptionlist element, the list of options can be embedded into the foil. 
        
        The foilgroup is required to have an options attribute which should be a perl list of possible options for the student.

        A tolerance parameter should be used to determine how closely the system will require the student’s answer to be in order to count it correct. The tolerance will default to zero if it is not defined. The tolerance parameter should always be defined for a numerical problem unless you are certain only integer answers are generated from your script and you want students to reply with exactly that integer.
        
        A significant figures parameter tells the system how many significant figures there are in the problem, as either a single number, e.g. 3, or a range of acceptable values, expressed as min,max. The system will check to make sure that the student’s answer contains this many significant digits, useful in many scientific calculations.

            When switched into exam ("bubble sheet") mode, LON-CAPA usually create wrong answers automatically. To specify wrong answers yourself, you need to provide an array of incorrect values in this attribute. You need to provide at least as many incorrects as 1 less than the number of bubbles on the exam. You can provide more if you want to.

            LON-CAPA will automatically perform some conversions between units of the same dimension when units are provided for a problem. You can provide an answer of "1.45 km" for a distance. If the computer expects the answer in cm, it will convert your answer before comparing against the numerical solution.

Format strings like "2E" (without the quotes) will display three significant digits in scientific notation. Format strings like "2f" will display two digits after the decimal point.

            This is a green curve the computer will display once the correct answer has been submitted. It is static, and can be given as a piecewise function.
            Since some problems will have multiple correct answers, this necessarily will only be a possible answer. Only the left hand side of the equation is necessary. For example, entering x + 2 will display the line y = x + 2.

This allows for a comparison of two points on the graph. The value of a previously defined label can be retrieved using the function &amp;fpr_val(), e.g., &amp;fpr_val('positive').

For the function itself, the 'percent error' is multiplied by the ymax-ymin; for the first derivative, it's multiplied by (ymax-ymin)/(xmax-xmin); for the second derivative, it's multiplied by (ymax-ymin)/(xmax-xmin)2; and for the integral, it's multiplied by (ymax-ymin)*(xmax-xmin).

            Chemical reactions use the following syntax:
            - Reactants are separated from products by '-&gt;'.
            - Individual reactants and products are separated by ' +' (leading space is obligatory).
            - Numbers preceding the first symbol of a chemical specie are considered to be stoichiometric coefficients.
            - Numbers appearing after the first symbol of a chemical specie are considered to be subscripts.
            - Superscripts are initialized by '^' and terminated by a space.
            - Ionic charges are superscripts composed of a number followed by a sign (i.e. '^2+').

      <div class="documentation">        Radiobutton Hint Condition
        
        The radiobutton hint element takes two attributes: answer and name. The name is the name of the hint condition, and the answer is an array. The first element of the array will be 'foil'; the remaining elements are the names of the foils that you require to have been checked by the student for the hint to be displayed. For example, if you create a radiobutton response problem with six foils named: granite, gabbro, gneiss, shale, sandstone and schist, and you want your hint named: igneous to be displayed when either granite or basalt had been checked your radiobutton hint would be as follows:
        
        &lt;radiobuttonhint answer="('foil','granite','gabbro')" name="igneous"&gt;&lt;/radiobuttonhint&gt;
        
        In order to trigger display of this hint you also need to create a hint condition (&lt;hintpart&gt;) that will include the text of the actual hint.

      <div class="documentation">        Option Response Hint Condition
        
        There are two types of option response hint conditions: one for standalone foils and one for concept groups. In both cases the option hint element includes two parameters: answer and name for standalone foils, and concept and name for foils grouped together in a concept group.
        For the answer parameter, the names and submitted values for each of the foils that are being included in the hint condition are provided in a hash, i.e., in the format: ('Foil1'=&gt; 'True','Foil2'=&gt; 'False').
        In the case of a conditional hint for a concept group, the format of the concept parameter is also a hash that links the name of each concept group included in the hint condition to either 'correct' or 'incorrect' - e.g., &lt;optionhint concept="('buoyancy'=&gt; 'correct','density'=&gt; 'correct')" name="fluids" /&gt;.
        If 'correct' is specified for a named concept then when the conditional hint is evaluated answers for each of the foils selected by a student must be correct for the hint action to be triggered. If anything other than 'correct' is provided in the concept hash in the optionhint element then then students answers will be compared with the set answers for the foils in the concept group and as long as at least one answer is incorrect (i.e., the concept group was not correctly answered) then the corresponding hint action will be triggered.

          - lines: Connect adjacent points with straight line segments.
          - points: Display a small marker at each point.
          - linespoints: Draw both lines and points.
          Draws a small symbol at each point and then connects adjacent points with straight line segments.
          - dots: Place a tiny dots on the given points.
          - steps: Connect points with horizontal lines.
          This style connects consecutive points with two line segments: the first from (x1,y1) to (x2,y1) and the second from (x2,y1) to (x2,y2).
          - fsteps: Connect data with horizontal lines.
          This style connects consecutive points with two line segments: the first from (x1,y1) to (x1,y2) and the second from (x1,y2) to (x2,y2).
          - histeps: Plot as histogram.
          Y-values are assumed to be centered at the x-values; the point at x1 is represented as a horizontal line from ((x0+x1)/2,y1) to ((x1+x2)/2,y1). The lines representing the end points are extended so that the step is centered on at x. Adjacent points are connected by a vertical line at their average x, that is, from ((x1+x2)/2,y1) to ((x1+x2)/2,y2).
          - errorbars: Same as yerrorbars.
          - xerrorbars: Draw horizontal error bars around the points.
          Requires 3 or 4 data sets. Either X, Y, Xdelta or X, Y, Xlower, Xupper. Xdelta is a change relative to the given X value. The Xlower and Xupper values are absolute grid coordinates of the upper and lower values to indicated with error bars.
          - yerrorbars: Draw vertical error bars around the points.
          Requires 3 or 4 data sets. Either X, Y, Ydelta or X, Y, Ylower, Yupper. Ydelta is a change relative to the given Y value. The Ylower and Yupper values are the grid coordinates of the upper and lower values to indicate with error bars.
          - xyerrorbars: Draw both vertical and horizontal error bars around the points.
          Requires 4 or 6 data sets. Either X, Y, Xdelta, Ydelta or X, Y, Xlower, Xupper, Ylower, Yupper. Xdelta and Ydelta are relative to the given coordinates. Xlower, Xupper, Ylower, and Yupper are the grid coordinates of the upper and lower values to indicate with the error bars.
          - boxes: Draw a box from the X-axis to the Y-value given.
          Requires either 2 or 3 data sets. Either X, Y or X, Y, Xwidth. In the first case the boxes will be drawn next to eachother. In the latter case Xwidth indicates the horizontal width of the box for the given coordinate.
          - vector: Draws a vector field based on the given data.
          Requires 4 data sets, X, Y, Xdelta, and Ydelta. The ‘vector‘ style draws a vector from (X,Y) to (X+Xdelta,Y+Ydelta). It also draws a small arrowhead at the end of the vector. May not be fully supported by gnuplot.

        The enclosed elements are parsed in a stable random order. The optional attribute show=“N” restricts the number of elements inside that are actually parsed to no more than N. N can equal the total elements inside. The randomlist element can be used to randomize problem parts by wrapping the &lt;part&gt; elements with a randomlist element. Note that when randomlist wraps &lt;part&gt; elements, that all students will work all parts only if show=“N” where N is the total number of parts wrapped. When N is less than the total number of parts wrapped, there will be gaps in the assessment chart, and also in the table of submissions for each student, corresponding to those parts which are never available to that particular student.

    Attribute <span class="nomattribut">id</span>:
    <div class="indentation">optional<br>type: <tt>xs:ID</tt><br>
      
        <div class="documentation">          This attribute defines a unique identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).
          
          Usage note:
          - This attribute's value is an opaque string: this means that web author must not use it to convey any information. Particular meaning, for example semantic meaning, must not be derived from the string.
          - This attribute's value must not contain white spaces. Browsers treat non-conforming IDs that contains white spaces as if the white space is part of the ID. In contrast to the class attribute, which allows space-separated values, elements can only have one single ID defined through the id attribute. Note that an element may have several IDs, but the others should be set by another means, such as via a script interfacing with the DOM interface of the element.
          - Using characters except ASCII letters and digits, '_', '-' and '.' may cause compatibility problems, as they weren't allowed in HTML 4. Though this restriction has been lifted in HTML 5, an ID should start with a letter for compatibility.

        <div class="documentation">          This attribute is a space-separated list of the classes of the element. Classes allows CSS and Javascript to select and access specific elements via the class selectors or functions like the DOM method document.getElementsByClassName.
          
          Usage note: Though the specification doesn't put requirements on the name of classes, web developers are encouraged to use names that describe the semantic purpose of the element, rather to the presentation of the element (e.g., attribute to describe an attribute rather than italics, although an element of this class may be presented by italics). Semantic names remain logical even if the presentation of the page changes.

Note that it is recommended for styles to be defined in a separate file or files. This attribute and the &lt;style&gt; element have mainly the purpose of allowing for quick styling, for example for testing purposes.
          
          Usage note: This attribute must not be used to convey semantic information. Even if all styling is removed, a page should remain semantically correct. Typically it shouldn't be used to hide irrelevant information; this should be done using the hidden attribute.

HTML5 extended this to any kind of media queries, which are a superset of the allowed values of HTML 4.
            
            - Browsers not supporting the CSS3 Media Queries won't necessarily recognize the adequate link; do not forget to set fallback links, the restricted set of media queries defined in HTML 4.

      <div class="documentation">        The HTML List Item Element (&lt;li&gt;) is used to represent an item in a list. It must be contained in a parent element: an ordered list (&lt;ol&gt;), an unordered list (&lt;ul&gt;), or a menu (&lt;menu&gt;). In menus and unordered lists, list items are usually displayed using bullet points. In ordered lists, they are usually displayed with an ascending counter on the left, such as a number or letter.

      <div class="documentation">        The HTML &lt;span&gt; element is a generic inline container for phrasing content, which does not inherently represent anything. It can be used to group elements for styling purposes (using the class or id attributes), or because they share attribute values, such as lang. It should be used only when no other semantic element is appropriate. &lt;span&gt; is very much like a &lt;div&gt; element, but &lt;div&gt; is a block-level element whereas a &lt;span&gt; is an inline element.

            This attribute is required in an anchor defining a target location within a page. A value for name is similar to a value for the id core attribute and should be an alphanumeric identifier unique to the document. Under the HTML 4.01 specification, id and name both can be used with the &lt;a&gt; element as long as they have identical values.

          <div class="documentation">            This was the single required attribute for anchors defining a hypertext source link, but is no longer required in HTML5. Omitting this attribute creates a placeholder link. The href attribute indicates the link target, either a URL or a URL fragment. A URL fragment is a name preceded by a hash mark (#), which specifies an internal target location (an ID) within the current document. URLs are not restricted to Web (HTTP)-based documents. URLs might use any protocol supported by the browser. For example, file, ftp, and mailto work in most user agents.
            
            Note: You can use the special fragment "top" to create a link back to the top of the page; for example &lt;a href="#top"&gt;Return to top&lt;/a&gt;. This behavior is specified by HTML5.

In HTML5, it is a name of, or keyword for, a browsing context (for example, tab, window, or inline frame). The following keywords have special meanings:
            
            * _self: Load the response into the same HTML4 frame (or HTML5 browsing context) as the current one. This value is the default if the attribute is not specified.
            * _blank: Load the response into a new unnamed HTML4 window or HTML5 browsing context.
            * _parent: Load the response into the HTML4 frameset parent of the current frame or HTML5 parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
            * _top: In HTML4: Load the response into the full, original window, canceling all other frames. In HTML5: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.

            Warning: event handler content attributes should be avoided. They make the markup bigger and less readable. Concerns of content/structure and behavior are not well-separated, making a bug harder to find. Furthermore, usage of event attributes almost always causes scripts to expose global functions on the Window object, polluting the global namespace.
            
            The EventTarget.addEventListener() function should be used instead to add a listener for the event.

        The HTML Teletype Text Element (&lt;tt&gt;) produces an inline element displayed in the browser's default monotype font. This element was intended to style text as it would display on a fixed width display, such as a teletype. It probably is more common to display fixed width type using the &lt;code&gt; element.

Concerns of content/structure and behavior are not well-separated, making a bug harder to find. Furthermore, usage of event attributes almost always causes scripts to expose global functions on the Window object, polluting the global namespace.
            
            The EventTarget.addEventListener() function should be used instead to add a listener for the event.
