I've never tried to do it from the doctype, but that information is
recorded in getSystemId and getPublicId in XMLResource.

Does your instance actually conform to the schema? I.e., is it a schema
with no target namespace?

The XMLResource doesn't get created if the schema is not present in the
instance. (I doubt I fully understand, what could be done with this?)

It is a chema with a targetnamespace., so if I remove it, would it work?

The resource itself is doing the loading so it must be created. Just
because ResourceSet.getResource throws an exception doesn't mean the
resource didn't get created.

Then the instance really must have that namespace to conform or you
should remove the target namespace and then the generated resource
factory should produce a resource that's able to open your content.

mmmh, that's right XMLLoadImpl
this would happen before the parsing.
String resourceURI = resource.getURI().toString();
inputSource.setPublicId(resourceURI);
inputSource.setSystemId(resourceURI);
inputSource.setEncoding(resource.getEncoding());
Ok, so I would retrieve the getSystemId/GetPublicId, translate the DTD
URI to my schema URI with a custom loader and then...Not sure how I
should tell the loader that my instance would/should conform to the
resolved. Could I use one of the options, to point to the schema location?

That's propably easier to achieve.

These things are populated from the information of what's being parsed.

While processing the root element, XMLHandler.getPackageForURI will be
called so that that point I suppose you could use the public/system ID
to locate package for the null namespace.

Yes, it should just work and in the end, one really ought to have a
schema to which the instance actually conforms...
