It seems to be invalid in HTML 4.01, but valid in XHTML 1.0. Why is there the
difference? Can that pose a problem when such a XHTML document is served as
text/html?

I created two test documents and compared. It (assuming you mean <pre>
elements containing <img> elements[1]) is invalid in both HTML 4.01 Strict
and XHTML 1.0 Strict.

I believe you. But
<pre><a><img src="image.png" alt="" /></a></pre>
validates as XHTML 1.0 Strict whereas
<pre><a><img src="image.png" alt=""></a></pre>
does not validate as HTML 4.01 Strict, when I used http://validator.w3.org/ for
validation.

Ok, if it helps. Sorry for not being precise in my original message.

Valid, but non-conformant:

Thanks, this clarifies the dilemma and gives me the reason to use different code.
