The context menu gets the value from the "href" of the anchor which is
also what gets copied and pasted to other documents. If we want to save
the user from exposing this then we want to make the anchor's href point
somewhere bland and generally inert. Clicking on a "Copy this Link"
allows the page's code to bring up some sort of edit box (like Google
maps) that contains an authority designating capability.

Ack, web pages, as far as I know, can't put things on the clipboard.
This is just about exposing the "right" thing to the web browser so it
can be copied by the user.

Does it make any more sense now? It would be nice not to have to do
this, but I can't see any way of keeping copy/paste safe otherwise.
