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