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
