*chuckle*   I see that your basicness is biting still ;-))

Apart from the fact that it lacks brackets, and thus needs an extra 
transformation, what does this give us?

What does this give us practically?

XSLT? I like it. For simple transformations IMHO it really rocks. With a 
relative small number of tags and some xpath it does almost all that is 
needed.

Do you remember at ApacheCon Europe, when the Xalan developers kept 
saying that XSPs were irrelevant because XSLT could do all? *chuckle*

I still don't honestly see th ebig difference between that and XSLT.
