Description

There are 2 schemas that we got from the plc4x project when they were experimenting with DFDL.

These schemas make use of XML Catalogs.

If you update their build.sbt to reference 3.2.0-SNAPSHOT, they fail with

```

If you remove the XML Catalog usage, and replace it with class-path relative names, then the schemas still work. But that shouldn't be necessary of course.
