The WF2 spec does not say anything about filtering autocomplete lists  
on pattern and Opera 9 does not do it. However, autocomplete entries  
that would fail form validation are not particularly useful.

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.

(Real-world case: The autocompelete menu for the document field at
shows ftp and file URLs in Opera 9 even though the pattern only  
matches http and https URLs.)
