I took a look through the XXE API and the developer's guide to see if I

This is a pretty advanced need given the flexibility of catalog-based
entity and URI resolution. No wonder you haven't found anything.
We would like to have our vDrive plugin make use of such an
EntityResolver so that our customers who have their own Dita
specializations (custom dtd's)
can use the XXE connected editor that we ship with, to open and edit
documents that use these specialized DTD's.
We already have a custom EntityResolver implemented and available, but
we just need a way to tell XXE to use that resolver when opening a
document as opposed
to using the dtd's that the editor ships with - is this possible, and if
so, could you point me in the right direction.
XXE exclusively uses this utility class:
com.xmlmind.xml.resolve.XMLCatalogs
http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xml/resolve/XMLCatalogs.html
to resolve entities.
It's basically a simple helper class leveraging "Apache XML Commons
Resolver" (which implements catalog-based entity and URI resolution; see
http://xerces.apache.org/xml-commons/).
I'm afraid there is no way to use a custom EntityResolver in XXE.

How to use a DITA specialization in XXE
---------------------------------------
<XXE_install_dir>/doc/configure/samples/topic_plus_tag/ contains a
configuration for a DITA topic specialization.
This specialization adds a <tag> element to the topic DTD. A <tag>
element has a required kind attribute. The values allowed for the kind
attribute are: "attribute", "attvalue", "element", "emptytag", "endtag",
"genentity", "localname", "namespace", "numcharref", "paramentity",
"pi", "prefix", "comment", "starttag".
This configuration has been created by customizing the stock DITA topic
configuration as explained in "Chapter 5, Customizing an existing
configuration",
