	=item * <option />: Allows you to add optional elements to the
	resource chooser currently these can be a checkbox, or a text entry
	or hidden (see the 'type' attribute below).
	the following attributes are supported by this tag:

	=over 4

	=item * type=control-type : determines the type of control displayed.
	This can be one of the following types: 'checkbox' provides a true/false
	checkbox. 'text' provides a text entry control. 'hidden' provides a
	hidden form element that returns the name of the resource for each
	element of the text box.

	=item * text=header-text : provides column header text for the option.

	=item * variable=helpervar : provides a helper variable to contain the
	value of the input control for each resource. In general, the result
	will be a set of values separated by \|\|\| for the checkbox the value between
	the \|\|\|'s will either be empty, if the box is not checked, or the resource
	name if checked. For the text entry, the values will be the text in the
	text box. This could be empty. Hidden elements unconditionally provide
	the resource name for each row of the chooser and allow you to therefore
	correlate text entries to their resources.
	The helper variable can be initialized by the user code to pre-load values
	into the controls:

	=over 4


	=item * Preloading checkboxes : Set the helper variable to the value you
	would have gotten from the control if it had been manually set as desired.

	=item * Preloading text entries : Set the helper variable to triple pipe
	separated values where each value is of the form resource-name=value

	=item * Preloading hidden fields : These cannot be pre-loaded and will always
	be pipe separated resource names.
