Bug#16233: XML: ExtractValue() fails with special characters

Browse Source 
ExtractValue didn't understand tag and attribute names
consisting of "tricky" national letters (e.g. latin accenter letters).
It happened because XPath lex parser recognized only basic
latin letter a..z ad a part of an identifier.

Fixed to recognize all letters by means of new "full ctype" which
was added recently.
