Check if :: follows name in which case it becomes a qualified name. @param atPos a natural number if we just read an '@' token, else -1 @param memberTypeFlags flags tracking whether we're a '.' or '..' child @return an XmlRef node if it's an attribute access, a child of a '..' operator, or the name

(int atPos, int memberTypeFlags)

     *     malformed XML expressions. (For now - might change to return a partial XmlRef.)
