Yes, I suspect that Saxon or its parser is stripping the node for some
reason. Thanks for helping to confirm it's not an oXygen thing.

The indent='yes' whitespace isn't actually the same ... it is inserted
by the serializer. and for one reason and another, isn't really
workable for me. (In the actual problem I am generating HTML output,
and in mixed content in the result, no extra whitespace is inserted
even with indent='yes'.)

I checked the Saxon -strip:none flag, which seems like it's supposed
to prevent this (though I have no DTD); I wonder what's up with it.

Cheers, Wendell
