ocp fails to cross build from source, because it fails running xa with
an "Exec format error". Usually, that indicates that the providing
package should be installed for the build architecture. While xa65
handles binary formats, the architecture it operates on is effectively
encoded into the package name rather than the package's architecture.
Therefore, Multi-Arch: foreign is appropriate. Once adding it, a
runnable version will be installed during ocp's cross build. I'm
attaching a patch for your convenience.

Hi David,

I have NMUed xa to delayed=10.  For your convenience I pushed all changes to Salsa at

https://salsa.debian.org/debian/xa

Please let me know if I should cancel the upload.

Kind regards
    Andreas.
