I took the time to nail it down:
- hello-world.html works, but hello-world.xhtml doesn't, for the same
content. .xhtml extension just makes dillo not recognize the file as
HTML, for any content. This is not the bug I had reported, though but
a new one. I will let you file it.
- The offending line that made my two .xhtml files not be recognized was
which is perfectly valid XHTML 1 as well as HTML, and works in
all .html files I have tried, including "hello-world plus
http-equiv.html.
I attach these new, simplified, test files. You should be able to
reproduce it with them. They are as simple as a conforming XHTML 1
document can get, except the one with the added http-equiv,
obviously. Please, unmark the report as unreproduceable then.
On a personal side, I would have appreciated if you had told me you
hadn't tried .xhtml extension. You would have saved me test time.

XHTML 1 is just a subset of HTML 4 that is XML conformant, so it has
been basically supported by dillo since its very first release, back in
1999. XHTML 1.0 became a W3C recommendation on 26 January 2000, when
dillo was just at version 0.0.4, and a lot of things have happened ever
since. XHTML is mentioned in the ChangeLog for version 0.8.4, which was
released on the 11 of January 2005, but that was so far as to the
validation feature, so it doesn't mean it wasn't supported beforehand.
application/xhtml+xml was finally accepted in version 2.2.1 (July
2011), so since then XHTML 1 should have worked flawlessly.
My reasoning for the severity is XHTML 1 has been there for ages and is
trivial to implement. There are tons of documents tagged as such around
on the web, so not supporting it makes it impossible to use dillo
nowadays as a general browser, which renders the package unusable
except for particular cases, hence mostly unusable.
Having found out the bug was just in accepting the http-equiv, and not
in any XHTML I document I am lowering severity to important.
If I had the time I would volunteer to provide a proper patch, but I
don't know this browser's code as well as ELinks', so can't promise
anything at this time. It should be trivial for the developers, though.
All I ask you is to confirm the bug was not coming from a
Debian patch and forward the full report to upstream. That's all.
