HTML+ includes the ABSTRACT element for this. The "Summary" HTTP
header should therefore be reserved for a brief description.

At some point in the future we may wish to extend HTTP
to allow clients to request named portions of the document.
Right now the #ID suffix is interpreted by the client, but there
is now reason why with a suitable HTTP method (e.g. "EXTRACT")
the server couldn't extract the contents of the named container
and send that rather than the entire document.
