Purpose:
- normalize attributes
- check attributes for well-formedness
- generate namespace aware attribute names (URI, prefix)
- build list of attributes for startElementHandler
- default attributes
- process namespace declarations (check and report them)
- generate namespace aware element name (URI, prefix)
