Hi, the page http://www.w3.org/TR/REC-xml/#charsets mentions in
a note, that some characters are discouraged, in essence all C1
controls excl. NEL and the 66 non-characters. 

The 66 non-characters consist of 17 planes * 2 (??FFFE, ??FFFF)
and 32 u+FDD0 up to u+FDEF.  This XML 1.0 document says u+FDDF
instead of u+FDEF.

The page http://www.unicode.org/Public/UNIDATA/DerivedAge.txt
claims that these 32 non-characters were introduced together in
Unicode version 3.1.   The normative [Unicode3] reference in
XML 1.0 4th ed. is based on Unicode version 3.2.

Regards, Frank
