- repair issue in sax.ElementTreeContentHandler
whereby attributes passed to startElement() would be mis-interpreted
as containing a namespace attribute, leading to a TypeError,
as well as where attributes with namespaces wouldn't be split
up correctly when passed to startElement().
- pass through non-NS aware attribute names as is; a ":" should just go to
ValueError
- use boolean test for attributes dict
