[Bug 4674] add definition of a dangling reference


           Summary: add definition of a dangling reference
           Product: SML

            Status: NEW
          Severity: normal
          Priority: P2

SML mentions dangling references in several places but does not define them.  I
believe a dangling reference is an SML reference, for which at least one scheme
is specified, but which is not retrievable using the retrieval mechanism
defined by any scheme the implementation supports.

Need to cover several cases:
- SML reference (defined elsewhere) with no child content
- ...with child content containing no sml schemes
- ...                          ... no sml schemes supported by the impl
- ...                          ... at least one scheme supported by the impl
Nb: if SML changes to support schemes via attributes on the sml:ref=true
element, more cases become relevant.
