RE: [xml-dev] local unqualified element names and default namespaces

My understanding is that <name> is required to be in no namespace, and
therefore this instance is not valid.

or something else?

The element in your instance is in namespace http://www.abc.com/, under the
rules of XML Namespaces. This isn't affected by the schema. The schema says
that you can only have a {}name element here, so this instance is not valid.
