Agreed, since I have been using URNs almost exclusively as namespace URIs. Fortunately, that's not what the schema spec states. Check out section 4.3.2 of the dec. 17 draft (http://www.w3.org/TR/xmlschema-1/#schema-loc) which describes the 'xsi:schemaLocation' attribute. Also, see http://lists.w3.org/Archives/Public/www-xml-schema-comments/1999OctDec/0054. html for James Clark's comments on this attribute. > It is of course > not a violation of the namespace spec, Yes, but if schemas required xmlns to be a URL that refers to the schema definition, the utility of XML schemas would be greatly diminished given the current XMLNS recommendation.
