Rick Jelliffe comments:
The paper mentions the general problem with converting grammars of the class that corresponds to RELAX NG to Schematron. However, the two leading grammar-based schema languages are in a less difficult/powerful class, and actually fail to make available to users the very thing that regular grammars might provide over XPath: the ability to identify and treat differently the same element when it appears in different positions (to wit, the XSD Unique Particle Attribution rule.) However, of course, it is not necessarily true that the pattern of constraints being expressed by the RELAX NG schema could not also be described, in a very different way, in ISO Schematron using thought.

Rick Jelliffe comments: since this paper was written based on Schematron 1.4, there have been several improvements to Schematron that meet gaps suggested by the report, including in the areas of modularity, keys, default values (simulated by ISO Schematron 2016 “properties”) and inheritance (ISO Schematron “abstract patterns”).

Rick Jelliffe comments: since this paper, there have been several developments or techniques developed which means that Schematron can be marked as “Yes” for all the items in the scorecard: 28/28. For example, ISO Schematron 2016 properties allow (in effect) attribute defaulting; using XSLT2 provides regular expression assertions on strings. An earlier version of the report mentioned the provision of element checking using regular expressions; this can indeed also be done in Schematron using the technique in my O’Reilly blog Can Schematron use grammars to test assertions? (Contrast with XSD 1.0 which had 15/28 Yes (several with limitations), 3/28 Some and 10 Noes.) XSD 2.0 has improved this somewhat by adopting an mildly unsatisfactory kind of XPath assertion testing.
While it was entirely appropriate and polite for this report to avoid allocating any one schema language as being universaly better than another for every situation, I did feel at the time that the results of the scorecards were so obvious that it would be difficult for an objective person (which I surely cannot be) to avoid suspecting that the grammar-based approach for schema was inherently defective, except for some niche uses such state-machine-driven editors.

Rick Jelliffe comments: Other notes on alternative approaches to schemas investigated during my time at Academia Sinica Computing Centre can be found at schema page. I would like to note that there is no real material that describes one of the central motivations for Schematron: which is that Schematron was developed in part as a response to the suggestion from Taiwanese academics that formal grammar theory was not intuitively credible to Chinese in the way that it might be to Westerners, in that their concept of language was based on the ideograph rather than discrete words. This raised the question, what would a schema language look like that did not have this potential cultural bias?
