Just in case anyone's interested, I sent an email to the libxml mailing
list (xml at gnome.org) to confirm this. The response I got was rather
terse (somewhat understandably, but not entirely). Anyway it equates to
this: If you want to XInclude something as XML it must be well-formed.
This is correct behaviour according to the XInclude spec (see section
4.2). Our particular issue was that this was not true as there were
unresolved entities because of the lack of a DOCTYPE declaration
referencing a DTD that would resolve them (see XML spec section 4.1).
Hope this clears things up once and for all!
