Pointers in RDF review

Group:
Attached please find my edits and suggestions for the most recent Pointers
in RDF document at:

http://www.fundacionctic.org/uaw/ERT-WG/2009/EARL_draft.html

Some chief edits and questions:
Note: For all of these major edits, the original remains in comments prior
to the edit. My suggestions begin with '<!-- MAS -->'. Minor edits (e.g.
spelling, typographical) are not noted.

1. rewrote use cases section; still think we could use one or two other use
cases
2. rewrote description of Pointer class; spec says this could be used
directly but calls it abstract. I suggest leaving it as abstract and
requiring the use of subclasses either in the specification or created
elsewhere in other vocabularies. Also, with this approach, there should be
a Related Classes
section (see PointersGroup class, for example) that points to subclasses in
this spec.  If we want to permit direct use of the Pointer class, then an
example should be provided.
3. rewrote descriptions of RelatedPointers and EquivalentPointers classes
4. didn't modify it, but recommend that the description for SinglePointer
look much like that for Pointer class; make it abstract and require the use
of more specific subclasses
5. in the example for CharSnipetRangePointer, we refer to cnt:chars. Does
this mean that processors of Pointers in RDF must also know how to process
Representing Content in RDF? (May have already discussed this but couldn't
find anything in minutes.)
6. Is a pointer property along with a Pointer class going to be confusing?
Is there another name for the property (e.g. memberPointer)?
7. starting with Section 3 Properties, the 'in domain of' and 'in range of'
lists refer to earl:xxx QNames; should these be ptr:xxx QNames?
8. rewrote abstract but still needs work
I did not review the apendicies, although quick glance shows them
acceptable for a first draft.
