I think so too.

Then, if client discovers an linked LDPC, then this is the clue that it is a writable resource.

When a form is submitted, the processor (indicated by the 'action' parameter) is doing something pretty similar to a LDPC. I suppose the HTML equivalent of issue-73, would be "list all of requests that have been processed". For me, this isn't very interesting because the information I need is in the documents I am browsing.
