I've included an xml and a dtd file in my Resources folder (This is a
Winforms VB project in VS2005.) I'm planning on using the xml in Resources
as a 'template', just load it and change values. The beginning code is:

Dim xDoc As New XmlDocument
xDoc.LoadXml(My.Resources.NameOfXMLFile)
... do some stuff to XDoc

Given that, is it possible to use a DTD in Resources to validate the XML?

(I admit I'm having some trouble following the documentation on this point.)

That should be possible by using a custom implementation of XmlResolver
that ensures that the system identifier is resolved by loading the DTD
from the resource.

That's just it. The basic ref states that it 'Resolves external XML
resources named by a Uniform Resource Identifier (URI). ' Does this apply to
this situation?

Based on your previous post where you have
<!DOCTYPE BDD SYSTEM "EAI.dtd">
the EAI.dtd is a (relative) URI that needs to be resolved to load the
external DTD. If you put that into a .NET assembly as a resource then
you need to provide a custom implementation of XmlResolver so that the
XML parser finds the DTD in the assembly.
See
http://www.hanselman.com/blog/LoadingXmlSchemaFilesOutOfAssemblyResources.aspx
for an example, it deals with schemas but the mechanism is the same
whether the parser needs to access a referenced DTD or a referenced schema.
