Yes, apparently this is so. But I consider that to be a "private 
agreement" and not part of HTML. And I am not against it. I am 
against the fact that there is nothing in the source code of e.g. 
Wikipedia or MathML 2.0 (which follows the same cowpath - plus it 
also uses <blockquote> for indenting) which informs us that this 
is LaTeX.

There has been some debates here about whether User Agents, in 
particular screen readers, should rely on heuristics to detect 
what should have been written in @alt etc. I am so free as to 
place Ian on that side of the debate.

But here in _this_ case, suddenly we hear from what I am so free 
as to characterize as "the other side", that putting LaTeX source 
code into @alt - just like that - is OK.

There should be a microformat or something, for how to put LaTeX 
into @alt.
