Good idea, but it doesn't quite work.  XML is very rigid in saying
that all the characters have to be Unicode characters (which the Euro
is quickly becoming).  So let's take for an example the current 
identifier of The Artist Formerly Known As Prince.  Even if I have
an encoding in which this is available, say at code point 12352, that
doesn't make it into a Unicode character, or usable in XML.

Non-Unicode *encodings* are OK (e.g. ASCII).  Non-Unicode *characters*
aren't. -T.
