Right, we'd do it the same was as in Document, with a Map set to null 
unless special attributes were added.  So if you want base URIs and 
such, you make a Map and populate it with the bases.  Same for line 
numbers.  We don't have base uri support in Element right now for two 
reasons.  One, Rusty never sent in the patch.  Two, it would have added 
yet more memory usage.  It'd be nice if it was optionally added.
