Dear Jeni,

Thanks again!

Rephrasing my question about how to fill in such an identifier in a Spy-made XML
document,
I have a last question: Assume that I want to make a query and I have to fill in
such an identifier
(or any string, for that matter) in which there is a middle dot (or any other
allowable Unicode
character), what then should I do, since there are no keys on my (US) keyboard
with such characters?

Regards,
Hans
