I don't think DefaultNamespace is a good name, as this is not related to namespaces at all.
Right, that's probably similarly confusing as I found the heading "Implementing namespaces with the namespace class" in the lxml doc ;-) How about renaming this to "Associating custom element classes with namespaces"
Of course one would have to think about what default registry key/URI to use for the fallback, I simply took '*'.
Not a bad choice, as it's already used in getiterator(), findall() etc. Although no-one can prevent you from using '*' as a namespace URI...
Is there some string literal that is actually invalid as a URI? Maybe s.th. like this would be best. Or maybe remove the _utf8() conversion for the namespace registry keys and use some AnyNamespace object as the default dict key.
I think a better API would be an explicit module level function for setting the default element class.
The nice thing about staying close to the existing solution is that it is still possible to have per-tagname-registered custom element classes, if you wish.
