1. is no good here because the XML document is the application's document
(e.g. a Word doc) and the document may be moved to a different directory or to
a different computer which has the app installed somewhere else.
I'm not sure what the difference between 2 and 3 is, but this seems to mean
that I need to hardcode the DTD install path at compile time. Have I
understood this correctly?

No, check out the API docs for the EntityResolver class:
http://xml.apache.org/xerces-c/apiDocs/class_EntityResolver.html
If you're using a SAX parser, it's a method you can use to resolve
external ENTITIES (either PUBLIC or SYSTEM).
One question I have is why is this only in the SAX interface, what
about DOM?
