The design message I metioned was:


An explicit assigment might be the best long term approach if it is also
available in the main part of the query, otherwise a syntax that is
specific to the SELECT clause seems more appropriate.  To be compatible
with the results format as it stands, there needs to be a variable name
- that could change to a more general label - but just positional does
not work because the XML results format omits unbound variables, not
record them explicitly.

What was the issue for SQL with ambiguity that you worked on?  Was it
syntactic ambiguity or an interpretion/associativity ambiguity?
