I have the problem that the value of a token appears to be more

When parsing the expression "fn:false()", I get a QNAME token with
the value
"fn:false" -- what I expect & want.
However, when parsing the expression "false()", I get the token
NCNAME with
the value "false(". The token is right, but I don't want the
parantese to be
included.
This is frequently asked question: The Flex lexer merely provides a
pointer to the identified text in a buffer, temporarily '0'-
terminated, and in order to preserve that in subsequent lexer calls,
you need to copy it over. The Bison parser does indeed make several
calls to the lexer before the rule action is invoked.
