I like this idea except that your chances of the W3C adopting it are likely slim and none, so
is any idea of splitting XML 1.0 and "Namespaces in XML" into two different types of documents
so that applications are free to choose which method they want to use in their applications
without having to worry about handling the ambiguities that arise from combining XML 1.0 data
and "Namespaces in XML" data together all at once.  A clean break between the two
specifications I think would be good for XML.  It would end the namespaces issue as people who
want and need to use "Namespaces in XML" will use "Namespaces in XML" and those who don't want
to be bogged down with the complexities of "Namespaces in XML" or would prefer to use a
different method of managing unique names could choose to do so.  I just feel like some people
have the attitude that I will be using "Namespaces in XML" whether I like it or not.  Please,
lets formally split these two obviously different document formats for the good of XML and end
this namespaces issue right now.
