There should be ways of permanently getting rid of the warning without
having to disable the title page.  Google should know them.

The log file contains lines like the following:

--8<---------------cut here---------------start------------->8---
LaTeX Warning: Reference `sec:embedded-data' on page 3 undefined on input line 
9.


LaTeX Warning: Reference `sec:xml-summary' on page 3 undefined on input line 12
.


LaTeX Warning: Reference `sec:xml-summary' on page 3 undefined on input line 12
.


LaTeX Warning: Reference `sec:workfl-pres-pdf' on page 3 undefined on input lin
e 15.
--8<---------------cut here---------------end--------------->8---

The linebreaks are inserted by pdflatex.  That means the regular
expression for matching the "on input line <line>." part would have to
be able to deal with linebreaks after _every_ character, which it
currently does not.  Does anybody know if the insertion of these
linebreaks can be turned off?

No, that's from TeX Live 2007 as provided by Debian.

I was rather surprised that my version did not produce an exclamation
mark because I thought this was standard behavior.
