Description
Updated HAVE 2.1 DRAFT schema to merge/integrate elements from previous HAVE 1.0 schema.
Kept the original edxl-have2.1DRAFT.xsd structure.
Archive contains supporting schema required to validate edxl-have2.1DRAFT_v0.4.xsd
Changed some (not all) type names to include 'type' to distinguish from elements that use the corresponding type.
