Now that's an interesting problem, one that goes way beyond the nuisance
of DTD syntax leftovers in a schema-based world.
It seems that entity references may in fact be vocabulary-dependent, and
while DTDs were probably not wise to mix them so thoroughly with
structural declarations, there are good reasons for believing in such a
connection.
Maybe context-sensitive entity reference processing is going too far,
but it's not difficult to implement, especially as I'm already building
a preprocessor with parser logic built into it. Adding context
information to Ents rules looks like it will be one of my early use
cases.
