Ok, fair enough. However, I think the words "such as" does not make
the assertion sound particularly definitive. I think it MUST that
widget engines support the APIs and a SHOULD that they support updates
and sigs.

New text:
"A widget user agent is a user agent that attempts to implement this
specification. A widget user agent MUST also support the
[Widgets-APIs]. A widget user agent SHOULD support the
[Widgets-DigSig] specification and the [Widgets-Updates]

As you did, I removed reference to the fictional [Widget Security]
specification :)

I need to discuss this change with the editor's of the Widget Dig Sig
spec before doing that. I'll get back to you shortly about that.

Kind regards,
