Hi,
I have an XML that has a DTD declaration and also uses schemas with
different namespaces. The DTD contains only entity references while the
structure/grammar of the document is defined by schemas. While editing the
xml in the XML editor (bundled with WTP), the content assist and
validation work based only on the DTD. The schemas are ignored even if the
root element comes from one of the referenced schemas.
The content assist and every thing else work as desired (correct
proposals, warning, errors, etc) when the DTD declaration is removed. I
assume that when both DTD and XML schema are used in the instance
document, the XML editor considers only the DTD. Is it possible to
configure this feature so that both DTD and xml schemas are used. If need
be Ill extend SSE to provide an editor for the requirement. Any help is
greatly appreciated.
Thanks in advance.

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.
