Support XSLT Transform capability in BPEL Assign activity

Test out and clarify the support for the BPEL XSLT Transform capability in BPEL Assign activity.

I used the Assign Property Editor and chose Expression from the From drop down list, used Expression language Same as Process(XPath 1.0 in BPEL 2.0). I seem to have a bit of a problem with the code completion. control spacebar just lists my variables. If I then type in bpel: and hit control space, I see the bpel:doXslTransform(...). However if I select it I wind up with bpel:bpel:doXslTransform(...).

Also, the Editor created it with the ![CDATA. Is this correct? It seems that

<bpel:copy>
<bpel:from>bpel:doXslTransform(...)

is sufficient.
