I think the desired effect can be formulated by saying that when
the XPath expression in the id constraint selector is evaluated,
the 'function implementations' property of the dynamic context
is empty except for the SML 'deref' function.

This has the advantage that we do not need to write BNF to try
to handle the complexities of QName prefixes.  It makes it
easier to modify or adjust the set of available functions in 
future; that may or may not be an advantage.
