I don't agree. It would encourage developers to misuse XML by 
treating actual characters and character references differently.

What's in the TODO list is a proposal to be less aggressive about 
escaping non-ASCII characters with character entity references when 
the specified encoding allows them to be represented literally. 
That's reasonable. Round tripping them from input is not.

Furthermore, practically, neither DOM nor SAX parsers give us any 
information about which characters are represented by character 
references, so it's really not possible to round trip this without 
rolling our own parser.
