To me, attrs.getValue ("", "href") looks strange, I would prefer 
attrs.getValue (null, "href"). But I could also live with the empty
string.  
I would not like if it is switchable, left to the parser, or both
allowed.

I would suggest that only namespace interning is required: 
namespace URIs will be a small set of long strings, and
you do not meet them often while parsing. 
I think interning all names would slow down parsing too much (?).
