When Xerces parses an XML file, it assumes it is based on en empty DTD;
only when a schema declaration is found, the schema validator becomes
the active one.
Having an element declared in a non-empty namespace doesn't make it use
an XMLSchema, it's only a namespace declaration.
And any resource resolver is used only when trying to actually load an
external resource, e.g. when a xsi:schemaLocation or a DOCTYPE
instruction is found in the XML document.

If you were expecting to resolve the schema documents based on their target

you should use an API which has a resolver that will pass that

I really want to be able to do this usng xercesc, but I keep hitting walls.
I am not sure if it because of the API statement
The LSParser will then allow the application to intercept any external
entities, including the
external DTD subset and external parameter entities, before including them.
The top-level document entity is never passed to the resolveResource method.
but for however I try, when parsing ( with DOMLSParser ) an xml document such as
<foo xmlns="http://www.foo.org";>
...
</foo>
there is no callback to my resolveResource() method.
I am setting up my DOMLSResourceResolver with
conf->setParameter(XMLUni::fgDOMResourceResolver,myResourceHandler);
(I have tried using XMLEntityResolver classes also, to no avail).
Also (and this maybe related) - it appears to me that unless the grammar is
already loaded against the root element's namespace,
the xml document is treated as if it were a DTD instance, rather than a Schema
instance,
even though there is no DOCTYPE declaration, and there is clearly marked an
xmlns 'attribute' on the root element.
Any answers?
