So the big difference from this to the schema in
https://github.com/mozilla/openwebapps/blob/develop/docs/ACTIVITIES.md is that
one's keyed by action. Is the idea that keying by service URL is better because
it may be that an app wants to install several urls for the same action? It
seems more likely to me that the same service URL would handle multiple action
types.

I'm confused - this is modelled after the one in ACTIVTIES.md. Straight from
that page:

  services: {
    "http://webactivities.org/share": {
       type: [ "application/url", "text/*", "image/*" ]
       path: "/services/share.html"
    }
  }

Yes, some key words are different - but that's just a suggestion, and easily
changed.

Perhaps I'm puzzled by 'action' appearing in the attribute list. In the Mozilla
proposal, the url key is the action, and then in the attributes they have the
service url (they call it 'path'). That they could both be urls is a bit
confusing, but the semantics of the action url is the intent action, and the
service url/path is what url the browser should load.

No, you were right - I puzzled myself with this. Fixed up, key is now action,
and the keyword is "path" instead of "action"

+      "type" : "image/png",
+      "action" : "/services/share",
+      "title" : "Sample Sharing Intent",
+      "disposition" : "inline"
+    }
+  }
+}
