Hi Alena Li,

SOA supports *some* features of XPath 2.0 in XSLT, the infrastructure also supports XSLT 2.0, but JDEV mapper does not...
Check docs here...
Thank you, Vlad for the confirmation and the link. I was just thinking this may be something some developers have experienced.

Thank you again,
