                    922: Fig. "XML for Map in Figure" shows the XML representation of the
                    923: resource map shown in Fig. "Example of a Map in the Advanced Editor",
                    924: which is the format in which maps are stored. In the figure, however,
                    925: additional graphical map layout information generated by the Advanced
                    926: Resource Assembly Tool is not displayed. This graphical information is
                    927: optional to re-generate the same graphical layout when the map is
                    928: brought up again in the Resource Assembly Tool, and is not needed for
                    929: any other system functionality.
                    930: 
                    931: Maps can be generated by tools other than the Resource Assembly
                    932: Tool. In particular, an author might have some other representation of
                    933: a course sequence, which can be converted into a map using scripts. If
                    934: this map then were to be brought up in the Resource Assembly Tool, the
                    935: Tool would automatically generate a graphical layout for it. Each
                    936: entry of the map (resources, conditions and links) is stored in a
                    937: separate tag.
                    938: 
                    939: Resources and conditionsX<conditions> have to have unique ID
                    940: numbers. These numbers are automatically generated by the Resource
                    941: Assembly Tool when the entry is first created, or added to the entries
                    942: when a map generated outside the Resource Assembly Tool is first
                    943: retrieved. They can also be assigned by custom scripts or added in by
                    944: hand.
                    945: 
                    946: In the XML example, entry 1 is the start resource of the map. When
                    947: this map is accessed, the source (src) URL of this tag will be the
                    948: first resource rendered. Entry 2 is the finish resource of this
                    949: map. This resource will be the last resource in the sequence of
                    950: resources. Entry 6 is a problem resource with the given URL and title,
                    951: as well as the priority "mandatory". Entry 19 is a condition, which is
                    952: used by the link between entries 6, the problem, and 9, a
                    953: sequence. I<The final syntax for conditions has not yet been
                    954: determined.>
