Keywords are only expanded in the client, not in the server. So to
implement custom keywords, you would probably need to have a script
which the client would run to compute the value of your new keyword
so it could be expanded. However Subversion has no client-side script-
running mechanism, and the Subversion developers have strong security-
related motivations for not providing client-side script-running
abilities.

It probably could be done but I doubt it would be a high priority to
implement it. Would it be particularly useful to you?
Let's take your example of $prop:copyright$ -- if you want the
copyright to appear in the contents of the file, why not just put it
into the contents of the file instead of putting it into a property
of the file and then trying to include it via some new mechanism?
