Dear list, Apache Xerces-J says that it implements DOM Level 1 HTML (https://xerces.apache.org/xerces2-j/dom.html; see also https://lists.apache.org/thread/rflbm50vv9jwsbf5tys2mskxcqmo4z2q).
It also supports DOM Level 3 (https://xerces.apache.org/xerces2-j/dom3.html) and as such, supports bootstrapping (https://docs.oracle.com/en/java/javase/22/docs/api/java.xml/org/w3c/do m/bootstrap/DOMImplementationRegistry.html). However, in version 2.12.2, it seems that the Xerces DOMImplementation implementation classes do not advertise knowing HTML: hasFeature("HTML", "1.0") returns false. Relatedly, and more annoyingly for concrete reasons of proper bootstrapping, DOMImplementationRegistry.newInstance().getDOMImplementation("HTML") and variants return null. According to https://www.w3.org/TR/DOM-Level-1/level-one-core.html#ID-BBACDC08, I believe that this should be otherwise. Is it possible to correct this? Or am I mistaken in thinking that it should work? (I have posted this question to j-users but I get the impression that not many people read this list nowadays, I hope that re-posting here is appropriate.) Thank you.
