I haven't tried this, but have you tried defining the entity declaration
within the XML itself and not calling the DTD. Does the content
assistance work for the XML schema as well as for the entity?

Have you tried adding your DTD's public identifer to the XML catalog....
I think you may have to open a bug/enhancement request for this feature,
as I don't think the current loaders support both DTD and XSD mixtures.
You might be able to get around it by adding your DTD to a XML
catalog, and the same with your XSD. This way when you hit the
namespace for your XSD it can load via the namespace.

You could dynamically load the DTD if you knew the content type for the
XML file (i.e. it's always a particular type like XSL, DOCBOOK, etc),
and then dynamically load the DTD based on content type.
I think a bug should be opened to request that if a DTD and a XML Schema
are referenced, that both content models should be available. I think
currently the code is doing one or the other, but there are plenty of
use cases like yours that will have the need to intermix the two.
