Re: Information about usage of XProc 1?

We still use 1.0 quite a lot. But to my knowledge we haven't used XSpec with XProc, only with XSLT. Testing our pipelines mostly relies on regression tests that use plain diff to compare normalized outputs. I am not aware of other people who use XProc 1.0 with XSpec tests. People who still use XProc 1.0 for their pipelines are either stubborn or they have a really large codebase to maintain. Large XProc 1.0 codebases have probably been built up before XSpec added XProc support. Therefore I suppose it's Ok to drop XProc 1.0 support in XSpec.
