Michael,

Take a look here:

https://github.com/wendellpiez/JATSPreviewStylesheets

(If you have trouble seeing it let me know.)

In particular you can see code inside the Schematron branch, although
you will also need the XSLT branch.

Its approach is to create a normalized expanded version of the table
against which rules can be checked. Then your actual table elements
(rows and cells) can refer into the expansion, as a kind of map. (So,
the Schematron can call XPath as supplemented by XSLT.) This includes
indicators of cell row and column coverage as well as creation of the
ghost table cells that are a notable feature of OASIS/CALS tables.

If nothing else this may be worth looking at. You may need to tweak
your settings in Schematron to allow-foreign elements (for the XSLT
bits).

Enjoy,
Wendell
