You can, however, generate an element or attribute node which has no content, which serializes (or doesn't, depend on how you look at it) as an "empty string" and/or which processing software can easily "recognize" as an "empty string".

Why you would want to put an empty string into output, as (was it?) Mike said, is another question. I suppose if we reversed it to say "not put a string with any content" into output, it's easier to see -- yet that's easy, you just do nothing!

I love philosophy early in the day.

Cheers,
Wendell

No, not a truly empty string. XSLT is about generating a DOM-like tree of
nodes from which linear output, such as a series of bytes representing an
encoded string, is typically derived automatically. The production of a text
node requires the presence of at least one character. The character could be
a space or other non-printing character though.
