I suggest making it nullable and ignoring null in prose, that should be sufficient. (Gecko treats null as the empty string here, stringifies undefined at the moment; WebKit treats null/undefined as missing argument; Opera breaks YUI :-(.)

If not, then you can just use [TreatNullAs=EmptyString]. If it is, and you need null to behave like omitting the argument, you'll need to do as Anne suggested. I *could* introduce a [TreatNullAs=Missing], just like the [TreatUndefinedAs=Missing] that exists now, but it seems simpler just to handle this in prose. ================================================================================ 73588 1 robin 2012-09-11 14:04:19 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment. If you are satisfied with this response, please change the state of this bug to CLOSED. If you have additional information and would like the Editor to reconsider, please reopen this bug. If you would like to escalate the issue to the full HTML Working Group, please add the TrackerRequest keyword to this bug, and suggest title and text for the Tracker Issue; or you may create a Tracker Issue yourself, if you are able to do so. For more details, see this document: http://dev.w3.org/html5/decision-policy/decision-policy.html Status: Accepted Change Description: I made |url| nullable for both pS and rS, and ignored null in the prose. I didn't go with Heycam's suggestion because of current entry URL vs entry script URL. Rationale: It's nicer this way, and it breaks a major library. https://github.com/w3c/html/commit/cd7313f8b21c8069488c1efec603769745585990 85754 2 silviapfeiffer1 2013-04-08 22:29:42 +0000 FYI: added a further improvement from WHATWG commit: https://github.com/w3c/html/commit/54524c9626a8493598b4162266a54a6e3cd64ff9
