But I do have access to thousands of XPath-ish expressions which denote the structures that may be present in instances of the XHTML variant. Here's an example of one of the XPath-ish expressions:

Maybe Hans-Jürgen Rennau's paper on location tree is a start:
Rennau, Hans-Jürgen. 2017. “Location Trees Enable XSD Based Tool
Development.” In XML London 2017 Conference Proceedings,
20–37. London, United Kingdom: XML
London. https://doi.org/10.14337/XMLLondon17.Rennau01.
IIRC it describe a program that generates all possible locations
described by an XSD.
Hope this helps!
