SGML, on which HTML is based, says that the stuff inside attribute value
literals (i.e. inside the ""'s in ALT="...") doesn't get parsed for tags.

Now we could go ahead and parse it anyway, but that would be a strange
use of the technology.

The functionality that you're asking for has been in the HTML+
proposal for some years now: it's called the FIG element.

Your example would look like:


<FIG SRC="pictures">
<PRE>
   ._.
  /   \
 /     \
/-------\
 |   |_|
 | __  |
 | <A HREF=door.html>||</A>  |
</PRE>
</FIG> My House !


The most recent specification proposal is:
