Good. Now, where do we find functions like "is_xml_letter()" or "is_xml_nmtoken()" or "is_xml_name()"? The ASCII isalpha() etc. won't do because we need to allow accented characters etc., unless we want to disallow them. I couldn't find such functions by grepping in Subversion and apr/apr-util, though there are some header files that appear to contain tables of the relevant classifications in apr-util/xml/expat/lib/*.h.
