Firstly because I've yet to see any others survive in the context of a
dynamic document, I also believe non-author inserted content is common in
these final form rendering XML apps (XHTML/SVG) which introduce problems
which aren't there in XML as a data format land.

I insert content in all the HTML I render, which means collisions are
likely to occur, so we need to ensure that the methods work, I'm not
confident that having content contain the prefix will do that, anyway the
discussion has got into a little too much detail considering no-ones
really looked at doing it.

that would be fine, as there's no ambiguity about what it applies to, yes
it's ugly, but ugliness is less important than being unambiguous, many
people can't even understand the xlink namespace - we should be
protecting them from the confusion, and I think just uri is the only
sensible solution (and the ugliness is down to the general namespace
