I checked Calabash upstream page and they have Saxon 9.5 branch [2]. I would
suggest you start packaging that and get it into Sid first.

The reason I cannot upload 9.6.0.7 nor 9.7.0.1 to Sid is because they break
reverse dependencies. If you are willing to help me create patches for those
reverse dependencies and forward them upstream we could proceed with at least
uploading Saxon 9.6.0.7 to Sid.

There are already 3 Saxon versions co-installable:
libsaxon-java
libsaxonb-java
libsaxonhe-java
I would rather prefer to get rid of at least libsaxonb-java in the future.

I tend to dislike this approch.
