I've been going through the notes provided at [1] and only two
incompatibilities still exist between the API structure of the Mozilla
Contacts implementation and the W3C Contacts API (pending more complete
tests on the normative requirements included in the W3C spec of course):

- W3C API includes error codes rather than strings for error callbacks. Any
feedback on what works best here? Codes might be useful for I18n error
reporting although messages are much more direct and easily understandable
(and can contain reference error codes if required). Any recommendations or

- The ContactFindOptions.updatedSince attribute has been changed to accept a
Date object. We have this object in the JS environment so it makes sense to
use it. Initially it was defined to be xs:datetime (as included in the
Mozilla impl). Similarly, birthday and revision attributes on the Contact
interface also now accept Date inputs.

- 'API invocation via DOM events' is not implemented in Mozilla, though the
section is currently non-normative feedback on this would be good from the

That is all I could find and otherwise the Mozilla implementation is
conformant to the W3C spec.

Briefly, the following changes have already been added to the spec which
address other issues listed at [1]:

- The special operation 'caller' has been added to the Contacts.find()
operation. This method now acts according to its definition in the WebIDL
spec [2] (and the Mozilla implementation).

- A default ContactFindOptions.multiple value has been defined as 'true'.
