A legalistic niggle, which I am sure Tim is aware of more
than anyone: "Names beginning with the string 'xml'
[case-blind] are reserved for standardization in this or
future versions of this specification".
XML-related standards such as Namespaces, XLink have already
broken the letter of this rule; but it doesn't seem
appropriate that anyone who thinks of a nice XML idea and
wants to propose it for standardisation should automatically
have rights to this namespace, even if he is a co-author of
the standard!
Some W3C process needed here...
