Hi Norm,

Thanks for this, I think this is a really good start.

So if I understand your proposal correctly, the main pipeline returns
the base URI of the source document (that is, not the serialized one),
and the compare pipeline then finds the serialized document + the
expected result based on this base URI. Right now, the locations of the
files are hard coded in the compare pipeline, but perhaps this could be
generalized? I mean, in most cases I expect the compare pipeline to
always do about the same thing:

1. Take the source base URI
2. Extract the file name from the base URI and use it for locating the
serialized document in /tmp
3. Extract the file name from the base URI and use it for locating the
expected result document in ../serialization/results
4. Run serdiff

We could then move the compare pipeline to a separate file and just
import it using <p:compare-pipeline href="...">.

A related question: how do XSLT/XQuery test serialization? Do they at
all?

Vojtech
