I have a RELAXNG schema which contains embedded schematron rules and a document which begins with two xml-model PIs like this: <?xml-model href="out/odd4crit.rng type="application/xml" schematypens="http://relaxng.org/ns/structure/1.0"?> <?xml-model href="out/odd4crit.rng" type="application/xml" schematypens="http://purl.oclc.org/dsdl/schematron"?> When I validate this document using the default CTRL-SHIFT-V option, or using a predefined validation scenario, only Schematron validation errors are reported. When I validate by selecting "Validate with" and specifying the schema URL again, errors reported by jing also appear. Is this the intended behaviour? Why? I am using <oXygen/> XML Editor 24.1, build 2022030807 on Ubuntu 20.04
