Thanks Henry, That's the point I wanted to make Since you said earlier that [[ b) Implementations SHOULD preserve PSVI properties across steps insofar as that is consistent with step semantics. It is implementation-defined what PSVI properties it supports overall, and what PSVI properties are lost by what steps. ]] Then it is obvious for me that you should have <p:choose> <p:when test="p:psvi-available('p:delete')"> <p:delete match="element(*,my:doomedType)"/> </p:when> <p:otherwise> ... Am I right ? Mohamed On Thu, May 8, 2008 at 3:44 PM, Henry S.
