For example boolean hasFeature(DOMString feature, [TreatNullAs=EmptyString] DOMString version); would be better as boolean hasFeature(DOMString feature, optional [TreatNullAs=EmptyString] DOMString version); 92049 3 annevk 2013-08-14 16:08:15 +0000 Could you list the others? hasFeature is not done because the feature should not be used. 92050 4 erik.arvidsson 2013-08-14 16:22:43 +0000 I still think doctype should be optional in createDocument. createDocument is still used since new Document has other issues. I'll file a new bug about that. 92052 5 erik.arvidsson 2013-08-14 16:47:28 +0000 For Document issue see https://www.w3.org/Bugs/Public/show_bug.cgi?id=22960 92054 6 erik.arvidsson 2013-08-14 17:39:08 +0000 (In reply to comment #3) > Could you list the others? hasFeature is not done because the feature should > not be used. It is actually only hasFeature and createDocument that has this kind of signature. 92088 7 annevk 2013-08-15 11:19:17 +0000 We could make it optional. But that doesn't make it optional in all browsers right away. It's not clear what the advantage is, other than it would more closely align with Chrome / Safari and less with Gecko / IE for the foreseeable future. Given that both Gecko / IE implement IDL (as I understand) making createDocument()'s arguments optional could be pretty trivial however and maybe that's okay with Olli and Travis? 92091 8 bugs 2013-08-15 14:19:42 +0000 I would not change hasFeature, just because it shouldn't be used at all. But making the last param of createDocument optional sounds ok to me. 92151 9 annevk 2013-08-16 10:42:53 +0000 https://github.com/whatwg/dom/commit/b6354d791f9998540a8de929da747f3945b005ff
