Re: call a week from today, right?

Well, any grammar that describes an XML instance with namespace support; how about converting to xhtml 5 using a grammar for markdown?

Or grammars for converting mathematic expressions in mathml?

Using a prefix as the non terminal name isn’t really enough on its own: there needs to be a way of associating a URI for the namespace.

I would support extending the attribute syntax, in a way which mirrors the XML syntax; something like:
> quote_type
> xmlns:   “http://www.w3.org/1999/xhtml”
> xmlns:m: “http://www.w3.org/1998/Math/MathML”

Other elements or attributes can then be associated with a namespace by the existence (or otherwise) of a prefix.

This is potentially significant for parsers, since to correctly create the required element, the namespace declarations will have to be parsed first.

Like many things namespace, there's clearly a lot of potential for ugliness here.  But I feel that's an argument to tie things down now rather than leave it much longer!
