Hi,
It has something to do with the rules matching on an attribute. I've
modified a bit the Schematron file to match on the element that contains
that attribute and the tests pass. I've attached these changed resources
(actually just /media-type.sch/ is changed).
I'm not sure why it behaves like that. I've reproduced the issue with
the command line XSpec 2.1.4 latest release. I recommend asking a
question in an issue on the XSpec GitHub project [1] or on the email
address xspec-us...@googlegroups.com . I'm sure the project maintainers
will know the cause and give you a recommendation.

Best regards,
Alex

Hello, all:
I have found creation of XSPec unit tests for Schematron assertions a
bit puzzling. I frequently manage to create Schematron which works
correctly for instance document validation but related XSpec scenarios
produce incorrect results. I may be repeatedly doing something
erroneous but have yet to determine what.
I am using <oXygen/> XML Editor 23.1, build 2021061407 which includes
an XSpec 1.6.0 framework.
An exemplar of my problem can be seen at
https://github.com/18F/fedramp-automation/commit/d023c719754ee5ed14dfc8a8991fbfafb82ff18b.
The Schematron (media-type.sch) works correctly with an instance
document (media-type.xml) but both XSpec scenarios (in
media-type.xspec) fail when the inbuilt "Run XSpec Test" translation
scenario is used.
Any and all suggestions are welcome.
Best regards,
Gary
