Re: Is there any easy way to provide XdmValue as a source for the standard XsltTransformer?

Hi Michael,

In fact, that's the objective of this exercise, to avoid
deserializing/reserializing from XdmValues that are the source/results of
cascading transformations orchestrated within Spring Integration.

Spring Integration has a message payload that is passed around within it.
I am shooting for an XdmValue message payload that can be transformed
without serialization.

This may well mean that I must forego the XsltTransformer for the
Xslt30Transformer, but I was hoping that there could be a simpler solution
since there is already a lot of implementation dependency on
XsltTransformer.

thanks for your help and best regards
