refs: smlif 3.3.2 P 1,4; smlif 3.3.3; sml 3.3.1, 3.3.2
all section numbers based on submission copy

There is a muddled distribution of content on the SML-defined schemes between
the two specs. I think a better approach would be to:

1. Define what a scheme definition must contain (in SML 3.3 or a separate
document entirely, possibly a Note... the SMLIF-imposed reqt pattern could
occur again, and I'd like to not have to rev SML for it).
   - MUST the content comprising/marking the scheme, e.g. sml:uri
   - MUST where the scheme's content occurs, e.g. child of reference element;  
     probably should ALWAYS be "where, wrt the ref element"
   - SHOULD whether or not the scheme MAY/MUST/etc be interpreted as an SML-IF 
     reference (SMLIF 3.3.2 defines normative rules if they are not explicit)

2. Define the sml:uri and sml:EPR schemes, current sections, making sure
   above conditions are satisfied.

3. Add to SML 3.3.1 the fact that its semantic includes the implication that
   it can be dereferenced using the default action for the scheme (as stated
   in SMLIF 3.3.2 P 4) so the two sections agree.

4. SMLIF 3.3.3 P 1 S 2 end, add reference to SML 3.3.

5. SMLIF 3.3.3 P 1 S 3 end, add reference to SMLIF 3.3.2

6. SMLIF 3.3.3 change heading "that are not" to "may not be"

7. Re-write SMLIF 3.3.3 P 1 (new text)
   SML [1] defines two reference schemes, the URI reference scheme and the 
   EPR reference scheme; it also permits new reference schemes to be defined 
   without limit.  Reference schemes 
   MAY be inter-document references in the context of SML-IF [SMLIF 3.3.2].
   Three consequences flow from this.

8. Re-write SMLIF 3.3.3 P 2 (new text)
   First, to successfully interchange models using reference schemes that
   are not inter-document references in the context of SML-IF, each reference
   element must be represented using least one reference scheme that IS 
   an inter-document reference in the context of SML-IF.  For example, [...
   rest of existing example].

9. Change SMLIF 3.3.3 P 3 "of ... [end of sentence]" to 
   "must agree on at least one
   reference scheme that is an inter-document reference in the context of 
   SML-IF for each reference element in the interchange set."

10. Change SMLIF 3.3.3 P 4 "sml:ref" to "reference"

11. SMLIF 3.3.2 work in the fact that something may also be an inter-document
    ref (or not) if explicitly declared by its reference scheme definition.
    If the ref scheme definition does not make any such declaration, the ref
    scheme's content is treated as ordinary content under the rules above
    for xs:anyURI.
