I believe this has the same status as "ExprToken" in the XPath spec. In
XPath, ExprToken is not specifically a production essential to the grammar.
All the tokens on the right-hand side are pushed down into other
definitions, but ExprToken collects all possible lexical tokens in one place
for the benefit of anyone writing a tokenizer. I think the same applies
here.
