> Xerces doesn't actually need xml-apis for the same reason that Saxon doesn't
> need it. The xml-apis library is used to provide a consistent set of XML
> APIs across different Java versions and implementations, but the XML APIs are
> included in the standard Java runtime library in all current Java LTS
> releases (8, 11, 17). We very likely can exclude xml-apis from Daffodil's
> dependencies safely, although we should do a lot of testing in diverse
> environments because the whole point of xml-apis is to provide a consistent
> set of XML APIs in these diverse environments. Still, Saxon also works in
> many diverse environments so if it can exclude xml-apis safely in its most
> recent 12.2 release, it seems that Daffodil can exclude xml-apis safely too.
> Note that Java 8 and Java 11/17 differ in how they package the Java runtime
> library. Java 11/17 have added module paths as well as class paths and moved
> the XML APIs into the standard Java module [java.xml (Java SE 11 & JDK 11 )
> (oracle.com)|https://docs.oracle.com/en/java/javase/11/docs/api/java.xml/module-summary.html].
> I do not believe Java's standard module path will cause a problem for
> Daffodil or Java applications embedding Daffodil libraries, but Java
> applications which use a smaller custom module path may need to add the
> java.xml module.
