Perhaps I'm just confused, but this seems to privilege the namespaces rec
way above the XML 1.0 rec.  Not only that, but #FIXED as a requirement for
namespace attribute declarations doesn't appear anywhere in the Namespaces
rec.  Rather than being conservative, I'd have to call this fairly radical.

It may seem grotesque to let people override the declarations in the
document, but I don't think it's that impossible to come up with cases
where it might actually be useful, and I can't see any reason why #FIXED
declarations should be mandatory.
