This clause describes the optional rendition module of HyTime, which includes both the modification facilities and the projection facilities. The module requires support of the scheduling module, and either or both of the "modify" and "project" options of the rendition module must be supported.
The modification and projection facilities of HyTime allow some of the parameters of an application's rendition of a document to be specified in a standardized way. Modification, which is described in 10.2 Object Modification, is used to specify processing of information objects. Projection, which is described in 10.3 Projection, is used to specify the semantic copying of events, modifier scopes, and projector scopes from schedule to schedule, perhaps transforming their positions and extents in the process. Events and modscopes can be projected with their objects and modifiers already modified in their source contexts, or with their objects and modifiers in unmodified form. A complete rendition can include several sets of modifications and/or projections; a container form for expressing complete renditions is described in 10.4 Rendition rule.
