A Saxonica client wrote today asking for facilities to specify the error
message that should be produced when validation against an assertion fails.

I was able to point him in the direction of Saxon's extension in this area,
documented here:

http://www.saxonica.com/documentation/schema-processing/extensions11/saxon.message.html

The client commented that it would be extremely useful to have this as a
standard facility in the spec.

Note that Saxon makes this available on all facets, not only xs:assert. It can
be very useful, for example, on the xs:pattern facet.
