HTML+ includes the ABSTRACT element for this. The "Summary" HTTP
header should therefore be reserved for a brief description.
Neat. Another twist for the next spin of the script, I guess.
However, (getting back to the original application) some of the files that
people want to have indexed may not have text set off as a formal abstract,
so <ABSTRACT> is not a 100% solution. I'm thinking of search-engine cover
sheets in particular. These frequently consist of nothing but an input
<FORM>, with no text that could be considered a proper abstract. For these
documents at least, I think I'd still need some other way of including
descriptive information which is not necessarily displayed, whether it's
<meta name="subject" value="...">
<meta name="iafa-description" value="...">
<!-- INDEXER description "..." -->
