OK, I understand the gist of the argument.  At the moment, it is fairly
easy to visually build a mapping between two different XSD schemas,
though, which produces XSLT.  There are a number of tools that do a good
job of this.  And my point was that *someone* has to come up with
mapping, bless it, and so on.  XSLT is technically expressed as XML, so
the mapping between two XML instances is expressed "as XML".  But I can
see some value in having the mapping itself represented as assertions.

Yeah, Margaret's follow-up clarified things for me.
