You have a good point. If UA is supposed to choose first type it
understands, then "tel fax" wouldn't work as a fax field, but "fax tel"
would. That's a nasty gotcha, so a selection algorithm should be more
sophisticated than that.

That's great!
If I may bikeshed a bit more: since HTML5 uses "tel", then
autocomplete[type] should use word "tel" too (instead of "phone") — just
to be consistent and use same name for the same thing.
Order of words in cc-full-name is inconsistent with name-full.
hCard uses "given-name" and "family-name", while current autocomplete
proposal has same "given-name", but uses "surname". It would be nice to
rename autocomplete types for consistency with hCard where possible
(unless they're consistent already with something else I don't know :)
