For images used in headers, one would expect
<h1><img src=src alt="Header text"></h1>.

Why should we have lower expectations about coding practise when 
it comes to putting LaTeX source code into @alt?

HTML 4 takes into account that <blockquote> is misused for 
indenting text and says that User Agents therefore "should not 
insert quotation marks in the default style".

Likewise, perhaps the cowpath to put LaTeX code into @alt needs to 
be taken into account. But in the first place we must realise that 
putting source code into @alt and assuming people/User Agents 
figure it out by themselves, is wrong.
