Thanks for those. Sorry, but I haven't looked at them yet. The one that I did run had 3/4 that passed, but I was running it to make sure that XSpec worked on this machine, so I didn't make a note of it.

What I have done is add Travis to 'Schematron/schematron' and 'Schematron/schematron-test'. In theory, if you rebase and push your branch, Travis should run schematron.bats from 'Schematron/schematron-test'. Can you try that?

The second half of the theory is that you should be able to add your new tests to schematron.bats and have Travis run them when you push to your branch. Can you try that?

All this is currently using the Schematron that is baked into XSpec 1.0.0. I haven't yet got it to the point of being able to use the Schematron from HEAD.

The failing tests are all but one due to bugs in the Schematron implementation:

Schematron/schematron#29
Schematron/schematron#69
Schematron/schematron#70
Schematron/schematron#71
