Description:
------------
function isValidString() uses this regular expression to check, whether string is valid XML name:

/^([a-zA-Z_]([a-zA-Z0-9_\-\.]*)?:)?[a-zA-Z_]([a-zA-Z0-9_\-\.]+)?$/

i.e. XML letter defined as [a-zA-Z], which is not correct - it must include wider range of characters according to XML specification. I think, it would be better, but maybe not the best, to use this definition of letter:

/^([[:alpha:]_]([[:alnum:]\-\.]*)?:)?[[:alpha:]_]([[:alnum:]\-\.]+)?$/
