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. 71009 5 contributor 2012-07-18 17:54:45 +0000 This bug was cloned to create bug 18271 as part of operation convergence. 73654 6 ian 2012-09-11 23:59:13 +0000 This will need some testing. 78518 7 ian 2012-11-20 08:12:51 +0000 Also consider: https://github.com/w3c/html/commit/cd7313f8b21c8069488c1efec603769745585990 82450 8 contributor 2013-02-01 00:19:00 +0000 Checked in as WHATWG revision r7685.
