XSLT planning

We are planning what features /improvements need to go in the next release for XSLT. We are making these decisions based on customer input and feedback. So I would like to hear your views on what you would like to see in the release of XSLT.

 

We are evaluating

 

XSLT 2.0 -

    1. Do we need to support XSLT 2.0 ?

    2. What are the most useful features of XSLT 2.0 that you would  like to see implemented? (like grouping , support for datetime etc)

    3. Do you believe support for the entire 2.0 spec is useful? If yes , why?

 

XSLT over large documents -

    1. What are some of the large document sizes that customers apply stylesheets?

    2.  Has anyone run into memory issues or perf issues while loading large documents ?

    3.  What were the workarounds you used for memory issues?

   

 

If there are other issues around XSLT/XPATH you would like to be specifically addressed in future releases, please let us know.

 

Looking forward to hear your comments.

 

Thanks
