Another aspect of this is that characters appropriate for identifiers in the
ASCII range will always vary, because they tend to be determined by
other aspects of the language in which the identifier is being defined for:
for example, "-+/%" cannot be used in languages that tokenize "-+/%" to be 
mathematical operators, "." cannot be used in languages that have a method or
field shorthand using ".",  [01-9] cannot be used in languages that take a leading
digit to signify the start of a number, and so on.

So it is the non-ASCII portion of the Unicode recommendations that are 
of interest, and these are pretty similar to XML 1.0.
