Summary: dashes in title causes XHTML error

Initial Comment:
I am running serendipity-1.0-beta2 (upgraded from
0.8-beta4 where I noticed the bug), and found the
following:  if I put dashes in a title (e.g.
"Title--more details") it causes the page to not
validate as XHTML 1.0 Transitional.

In particular, the following comments appear in the HTML:

<!--

xmlns:dc="http://purl.org/dc/elements/1.1/">
        <rdf:Description
                
rdf:about="http://mysite.com/blog/index.php?/feeds/ei_148.rdf"
                
trackback:ping="http://mysite.com/blog/comment.php?type=trackback&amp;entry_id=148"
                 dc:title="Title--more details"
                
dc:identifier="http://mysite.com/blog/index.php?/archives/148-Title-more-details.html"
/>
        </rdf:RDF>
        -->

and, in particular, the appearance of "--" in
'dc:title="Title--more details"' seems to cause a
validation error.

This results, for example, in Firefox 1.5.0.2
displaying --> after the entry.

The document linked to below explicitly states that for
compatibility (with SGML) the string "--" (double-hyphen)
must not occur within comments.  Having the double-hyphen in
the comments therefore violates well-formedness.  And, as I
have mentioned, including the double-hyphen in a comment
does cause the validator at validator.w3.org to fail.  I'm
not entirely sure of where the fault lies (admittedly
Firefox could probably handle this non-well-formedness
better), but I thought I'd bring this to your attention
again.  Thanks.

Sadly this is a strange display issue of Firefox. There's no
reason it turns those "--" into invalid characters. I also
cannot find any RFC that says "--" are forbidden in XHTML
(metadata). So honestly I think this is a thing that needs
fixing in Firefox. It does not show in RSS readers or other
browser AFAIK.
