Sorry, I cannot follow here. My proposal was to *add* these rules to
the grammar. To make the grammar more complete. So, the TMQL grammar
would contain nearly 60 productions + 6. I don't see a problem here?

I am not talking about the complexity of TMQL here. I *wrote* about
the complexity in my earlier proposal to restrict tm-content and
xml-content to the return clause, but it seems that it would not take
away the possibility to have XML everywhere since we support nested
queries, so that proposal is pretty useless.

Best regards,
