Re: Information about usage of XProc 1?

Thanks, Norm and Gerrit. I'm happy to hear that removing the 1.0 pipelines from XSpec sounds reasonable.

Just to be clear about what I'm referring to -- they are pipelines that you would use to execute an XSpec test suite that is testing either XSLT or XQuery. They are not related to testing XProc steps, which is a new capability of XSpec that has never supported XProc 1.0.

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.
