===> The verification XSD tools which are testing the validity of your
schemas (e.g. http://www.w3.org/2001/03/webdata/xsv )
are assuming that the URI is also the URL -- which indeed also
allows everybody to get the actual schema when they happen to
get a document referring to it in a straightforward way.
See you soon,
