I thought the XQJ libraries were needed by Saxon, but perhaps that's
no longer true. Perhaps it was never true, and I was just confused.

There's no straightforward way to do that because the data models are
all Saxon XdmNodes. The Validate step has the skeleton of a very crude
attempt to use Xerces instead of Saxon if you don't have a license for
Saxon schema validation.
