The definition for XML 1.0 is here:
   <http://www.w3.org/TR/REC-xml/#sec-starttags>
   <http://www.w3.org/TR/REC-xml/#NT-Name>
where the grammar says:
    Name	   ::=   	(Letter | '_' | ':') (NameChar)*
so a name has to start with what the specification defines as a letter 
or with '_' or with ':' where colon ':' is allowed by the XML 1.0 
specification but not helpful if you want to use XML with namespaces.
Letter is defined here:
   <http://www.w3.org/TR/REC-xml/#NT-Letter>
So it does not have to be a letter from the Latin alphabet a..z, but it 
has to be a character in one of the Unicode code ranges defined there as 
letter.
