Done:
	- Checklists (ChecklistT)  and Factsheets (FactSheetT) are conceptually correct
    - BiostatusT is conceptually correct
   - Low hanging fruit for use of ABCD is done, Some DC left that should be ABCD
  - Known used types moved to IASPS_Types.xsd. More to come
--LinearRangeT == NumericRangeT?  Fixed 11/5/06 at rev19
- Fix NumericRange to include units. Others too? Fixed 11/5/06 at rev19
-NumericRangeT Fixed 11/5/06 at rev19

-- gisin:Synonym typed as abcd:ScientificNameIdentified

To Be Done
-  Audit for places where we invent new concepts that are satisfactory in ABCD (Markus?)
-  Recode recursive elements as graphs a'la SDD for TAPIR ease
- Remove unused types (many?) from initial attempts
- Audit for remaining PlaceholderT and fill in
- Audit for TAPIR [recursion and weak typing]
- Provide sample documents
- Release for comment
- Fixed length strings

- Model salinity???
- Biology strings need fixed length
-Remodel elements with only enumerated content as complex elts with enumerations on an attribute
- Images in TaxonT
-Referencing in Images
- Refactor Types into BaseTypes
- Consider main elements at top level
- Look at TDWG/TAG time table for standards for taxonomic names, dates, geospatial data, temporal data, and measures
- Can we extend abcd:NamedArea (extended with its "sequence" attribute, or not) to represent our named areas. Maybe superceded by TDWG-GIG so perhaps wait. Lurk on the GIG schema?
- Fix taxonomic hierarchy to be like abcd

-should all empty enumerations be on attrs?
-write wiki entry about needs of application developers about what may be omitted in applications
- DatesOf: associate  "first" with "subsequent
- PathwayT remodel for enums
--Wiki: FreeTextT allows HTML??? if not, what about paragraph separators
--Wiki: How to sometimes relate Habitat to Impact

--Inheritance model (e.g. metadata): provide (optional?) attribute @inheritMetadata on entire tree
--Many things need optional metadata and optional text. Some need mandatory metadata and optional text.
