Hi Arnauld,
I'm new to Xalan, so you already helped me with mentioning
XSLTEngineImpl. However I find it quite difficult to get
something working based on the API docs. Can you please
give me some pointers where to look for additional info
or code samples?
Thanks a lot,
Achim

Thank you for all of these answers.
I understand that if a functionnality work in one way
it's not top priority to make it working in another way.
Trasnformation with DOM input work with XSLTEngineImpl and
it's enough for me.
Thanks again
I'm agree with you when you say
