Now it works for simple cases. I'm improving it to support the complete
grammar. It's an ongoing work.

The best approach would be to have a flex/bison parser but that's out of
my immediate scope right now. Once I have a working awk parser for
"create" I'll post it to get some feedback.

One suggestion: I think that we should split the current query dtd in two
parts: one for DDL (create) and another one for DML that includes the
former. This way the generated XML from my scripts could be validated
against the more compact DTD. It's a very small but useful change.
