--- Comment #4 from David Dorwin <ddorwin@google.com> ---
The "federation" scenario appears to be the main motivation for a "free-form"
value (i.e. comment #1 and comment #2). The assumption/implication is that the
license server is encoded in the PSSH.

However, this is irrelevant to this bug because URL extraction from initData is
not and should not be permitted (bug 25920). Federation is still possible, but
it requires metadata such as a manifest, which is increasingly likely with the
popularity of DASH and MSE.

I believe such URL extraction is the only use case discussed in the related
bugs for which an indication of the type of message/server (the proposal in
comment #0) is not sufficient. In the absence of concrete alternate proposals
for normative interoperable solutions, we should fix the current problem
(destinationURL) and get some implementation feedback and experience on the
message type solution.
