I suggest saying that potential autocomplete items (whether supplied
by the UA itself or read from a datalist) should be tested against
the datatype and the pattern of the form field being filled and
should only be shown if they match both the datatype and the pattern.
This assumes that the inclusion of such items is unintentional.
When the values are supplied by the UA (e.g. IRIs from the browsing
history), the inclusion of non-matching items certainly is
unintentional from the author's point of view.
What
if you wanted the user to be able to select from a fixed set of values
that fall outside of the pattern in addition to those that fit the
pattern?
Then you'd need to change the form validation phase in the spec.
Is the proper way to handle this to force web authors to write
these values into the pattern?
Yes. (Of course, alternatively, they can remove the pattern and
constrain the field by scripting.)
