Some comments and questions on Web Intents draft

A few comments and questions after taking another look at the draft:

2.2 Life cycle of Intents and Services
[[Registration is how a Service page informs the User Agent that it is
capable of handling Intents.]]
Technically, any page, not necessarily a service page, can include
registration markups (for other same-origin service pages). It would be more
accurate to say:
Registration is how a web page informs the User Agent that it or another
same-origin Service page is capable of handling Intents.
(Obviously this can use some wordsmithing...)

3.5 Registration Markup
[[Service pages declaratively mark themselves (or other same-origin pages)
as providing handling functionality for particular intent actions and types
using the <intent> tag.]]
Same argument as above. Maybe s/Service pages/Web pages/ ?

3.5.1  under Unregistering
[[Such explicit unregistration should be honored for any tag with a
same-origin href attribute.]]
[[The intent tags on the service handler page itself should be interpreted
by the User Agent as authoritative.]]
What happens if a service handler page includes an intent tag, but another
same-origin page erroneously includes a tag to unregister that service page?
Should the UA be required to check the service handler page if a same-origin
page attempts to unregister the intent to ensure that the service handler
page is authoritative? Contrast this with the scenario where a page
erroneously includes a tag to register a same-origin page for an intent. The
UA is required to check the service handler page upon invocation, ensuring
that the service handler page is authoritative. I'm arguing for symmetry
here - given that there is provision to ensure that at a page that
erroneously registers an intent for another page will be caught, there
should be provision to ensure that a page that erroneously unregisters for
another page will be caught as well.

Typos:
4.2 Steps 9 and 10: s/action type/intent type/ (multiple occurrences)
4.2 Step 9: s/continue fo/continue to/
