WebDAV could also define that the message bodies do not use namespaces, and
re-declare the namespace syntax so that "DAV:" is valid. However, I doubt
that anybody would want *that*. It would basically mean that on the long
run, an non-namespace aware XML processor is required, and that WebDAV
servers/clients would need to do namespace checking and mapping on their
