So I see! But many DTDs contain definitions for entities, which I
would like to use, rather than repeating those definitions by
\xmlsetentity in ConTeXt. Some XML documents also have their own
document-specific entities inside the DOCTYPE at the top of the file.

For example in legal agreements, I have something like:

<?xml version="1.0"?>
<!DOCTYPE blah SYSTEM "blah.dtd" [
    <!ENTITY us   "the company">
    <!ENTITY you "the customer">
]>

Where the stuff inside [...] is considered part of a document-specific DTD.
libxml2 handles this sort of thing with its "dtdattr" options; I
presume lxml has something similar.

So that's how to use \xmltexentity! I had seen that, but couldn't find
how to use it. Thanks!
