XML Namespaces Don't Need URIs (O'Reilly)
Michael Day
discusses XML Namespace issues on O'Reilly.
"
The decision to identify XML namespaces with URIs was an architectural mistake that has caused much suffering for XML users and needless complexity for XML tools. Removing namespace URIs altogether and simply using namespace prefixes to identify namespaces would make it easier for people as well as software to read, write, and process XML."
