Unless you have a real need, and a real need for pain, sticking with the XML "0.2" infoset (mixed content, unordered attributes, no other features) is a good idea, and is the minimum for a general XML processor. Lotta people like "0.1" (text only significant in leaves) or "0.0" (no text).

My most common problem with unparsers is that I want to specify which namespace prefixes are introduced and where, or to generate fragments when I know particular prefixes have been externally introduced.

The real mark of quality for me is optimized use of CDATA sections to reduce quoting overhead, but this is mostly politics: blowing up readers which try to draw a non-existent distinction between <![CDATA[><&]]> and &gt;&lt;&amp;.
