+;;
+;; This is a patch to work around a known bug in db2latex. Apparently
+;; xsltproc's error checking got a lot better since the authors of
+;; db2latex last tested this, so a clear language violation that
+;; xsltproc used to ignore now prevents xsltproc from working with
+;; db2latex.
+;;
+;; On FreeBSD you can simply drop this patch into the directory
+;; /usr/ports/textproc/db2latex/files/ and the ports system should
+;; take it from there. I've sent this patch off to the port
+;; maintainer but have not yet heard anything back.
+;;
+;; I don't really know whther this is the "right" fix, but it seems to
+;; work, and I'm pretty sure that the code this patch deletes does not
+;; work as it stands, so at worst the result after applying this patch
+;; should be no worse than the result without this patch.
+;;
+;; YMMV. If this patch breaks, you get to keep both pieces.

+;;
+;; This patches around a problem that I don't completely understand,
+;; and which may in fact be an xsltproc bug rather than a db2latex
+;; bug. Symptom is that the generated \title{} contains not only the
+;; book title but also the concatenation of all the chapter titles.
+;; This makes no sense, it doesn't happen with saxon, it doesn't
+;; happen with all versions of xsltproc, and attempts to trace this
+;; with --verbose and <xsl:message/> leave me more wondering whether
+;; it's me or xsltproc that doesn't understand the XSLT pattern
+;; matching rules.
+;;
+;; All that said, the change below prevents the bad behavior and
+;; should be completely harmless, so it will do as a workaround.
