Actually namespaces extend the notion of syntax in XML, so they're not just semantic. When you parse while namespace-aware, there are normative rules for that grammar that include having namespaces declared properly. I think you probably want to reference the notion of "namespace well-formed", so my suggested text could be adjusted to include that instead of just "well-formed". http://www.w3.org/TR/2009/REC-xml-names-20091208/#Conformance >If there is a suitable reference to some XML standard, that is probably >better.
