In my experience if you really care about anything you lose (CDATA 
sections, entity references vs. characters, etc.), that's a serious code 
smell that indicates a major flaw in the stuff. Yeah, the stuff that 
comes out may not be as nicely formatted for humans reading it with more 
or a text editor, but often even that can be fixed with appropriate 
options on the serializer.

I'm not sure exactly what this RIG thing you cited is, or what your use 
case is, but after skimming the spec, my nose is going nuts. This smells 
very bad. Why would anybody ever care about preserving attribute order? 
Why forbid CDATA sections? And section 12.1, "XML 1.0 features that, if 
present in an instance, will cause RCF1 to RCF conversion to fail" 
includes "Presence of control characters in the U+0000 to U+001F range 
other than TAB (U+0009), CR (U+000D) and LF (U+000A)." These are not XML 
1.0 features. If these things show up the document is malformed, 
irrespective of all the extra rules you're piling on top of raw XML. 
There's something deeply wrong here. :-(
