RE: XML and Queries (not XQL)

Title: RE: XML and Queries (not XQL)
It is useful to query the schema to provide a means
to construct a query.   This is straightforward in
terms of "string schlepping" in the interface to get
names.   Yes one can consider the content model
productions to constrain views of a sort.
As a query itself, no.  It doesn't work. In simplistic 
terms,  a query defines the conditions of the search;
the schema defines the properties of the search.  It
has been considered several times since the SGML
