                    926: Fig. "XML for Map in Figure" shows the XML representation of the
                    927: resource map shown in Fig. "Example of a Map in the Advanced Editor",
                    928: which is the format in which maps are stored. In the figure, however,
                    929: additional graphical map layout information generated by the Advanced
                    930: Resource Assembly Tool is not displayed. This graphical information is
                    931: optional to re-generate the same graphical layout when the map is
                    932: brought up again in the Resource Assembly Tool, and is not needed for
                    933: any other system functionality.
                    934: 
                    935: Maps can be generated by tools other than the Resource Assembly
                    936: Tool. In particular, an author might have some other representation of
                    937: a course sequence, which can be converted into a map using scripts. If
                    938: this map then were to be brought up in the Resource Assembly Tool, the
                    939: Tool would automatically generate a graphical layout for it. Each
                    940: entry of the map (resources, conditions and links) is stored in a
                    941: separate tag.
                    942: 
                    943: Resources and conditionsX<conditions> have to have unique ID
                    944: numbers. These numbers are automatically generated by the Resource
                    945: Assembly Tool when the entry is first created, or added to the entries
                    946: when a map generated outside the Resource Assembly Tool is first
                    947: retrieved. They can also be assigned by custom scripts or added in by
                    948: hand.

                    950: In the XML example, entry 1 is the start resource of the map. When
                    951: this map is accessed, the source (src) URL of this tag will be the
                    952: first resource rendered. Entry 2 is the finish resource of this
                    953: map. This resource will be the last resource in the sequence of
                    954: resources. Entry 6 is a problem resource with the given URL and title,
                    955: as well as the priority "mandatory". Entry 19 is a condition, which is
                    956: used by the link between entries 6, the problem, and 9, a
                    957: sequence. I<The final syntax for conditions has not yet been
