To be clear, I'm not proposing we put any policy in the Mallard
specification itself about what sorts of action links must be
supported. Action links are entirely up to implementations. It
may be useful to have a page somewhere that lists the action
schemes that various implementations use. But that would only
be a non-normative reference.

Yelp uses PackageKit for the install links. And at the moment,
if you have a package installed, the link is still there, and
you get a message saying it's already installed if you click.

I agree that's not ideal, but I don't want to block on calls
to PackageKit when rendering pages. So I'd need to add code
to modify pages after they've been presented to fix this.
This is possible now with the DOM bindings in WebKitGTK+,
but it's not at the top of my list. (It's high on the list,
just probably not high enough to make 3.0.)

At any rate, these are all implementation issues with specific
action link schemes, and shouldn't really affect the viability
of the proposed new syntax.
