So, make the spec return the empty string (or throw) on a serialization of this object type. 103334 1 zcorpan 2014-04-03 12:41:08 +0000 Blink serializes the value also (and escapes &<> but not "'). 103362 2 annevk 2014-04-03 16:30:54 +0000 Note that per DOM Attr is not a Node and therefore it would throw. 103365 3 travil 2014-04-03 18:14:03 +0000 Hmm, yes, I had forgotten that. WebIDL validation against the Node type would cause the API to throw a TypeError. So, I guess this case is already handled for me. 103368 4 travil 2014-04-03 18:24:58 +0000 I noted this condition in the spec to avoid any future questions (and to remind myself later when I forget again).
