From what I can tell, MSV is used in both cases, through
MSVValidationProcessor.
Before there was MSVValidationProcessor, we used ValidationProcessor,
which was delegating to either RNGValidationProcessor or
W3CValidationProcessor. The RNG validator used Jing, and the W3C one
used MSV. For some reason, we then switched to using MSV in all cases.

You could add a processor declaration for RNGValidationProcessor in
custom-processors.xml, and this way use Jing. If you are looking for yet
another validator, you will need to write some Java code. There is no
unified API for validators AFAIK.

Yes, the Pipeline processor appears to be using MSV in both cases,
through the MSVValidationProcessor class. However it does not use the
indirection in processors.xml and directly uses MSVValidationProcessor.
I think the architecture for those validation processors could be
improved somewhat. A couple of things come to mind:
o Pipeline processor should use an indirection in processors.xml
o Validation processor should be pluggable
