For example, suppose >I need an r-cedilla... in SGML I've used SDATA entities for that. Use the 10646 private use zone. We'll have to find some way to specify the meanings of code points in the private use zone (maybe XML needs an SGML-declaration equivalent that can do this); but with SDATA entities you equally have to find a way to describe their meaning, so I don't think you lose much by junking them.
