That's just not possible when DOM manipulation is involved.  It's 
possible to produce DOM's that can't be serialized in a form that 
round-trips to the same DO.  One can produce XML comments with embedded 
"--", one can produce HTML comments with embedded "-->", etc, etc.

Hmm.  That does appear to be what webkit does for XML, at least for 
comments...  I still don't see why that's desirable, since in XML 
comments really shouldn't affect behavior (and in particular, an XML 
parser is not guaranteed to preserve comment contents, according to 
XHTML 1.0 section C.4).
