xmllint will do XInclude processing if called with "--xinclude".  Independently, it will report all documents loaded during processing if called with "--load-trace".  However, when both of these flags are given, "--load-trace" list does not mention documents included via XInclude.

I can imagine why this might be the case if XInclude processing happens in an earlier and very distinct phase.  However, I am using "--load-trace" for dependency tracking and I need to know about *all* the external documents on which a given XML document depends.  That definitely includes files included via XInclude.

Is this a bug?  If not a bug, is there some other way to obtain the list of documents pulled in via XInclude?  I considered writing an XSLT script that operates with XInclude processing off and searches for <xi:include> elements, but that won't really work.  It will only discover inclusions at the topmost level; it will miss inclusions within included fragments.

As one might expect, the same problem affects xsltproc.

[I originally asked about this issue on <xml@gnome.org>: <http://mail.gnome.org/archives/xml/2007-September/msg00038.html>.  There were no replies about about three weeks, so I'm now putting this into the bug database instead.]
