For more details, see this document: http://dev.w3.org/html5/decision-policy/decision-policy.html Status: Did Not Understand Request Change Description: no spec change Rationale: see comment 1 59187 3 annevk 2011-10-29 07:55:10 +0000 I think empty string classes or annotations should never be created. I do not have a good alternative for empty start tag names. (Other than emitting "<", which I'm not terribly fond of.) 59197 4 ian 2011-10-29 16:13:37 +0000 Without a good alternative, I don't know what to do. 59198 5 annevk 2011-10-29 16:17:55 +0000 Before appending a class or annotation, do an empty string check (probably after whitespace normalization/trimming). 59229 6 ian 2011-10-30 17:49:08 +0000 So leave the empty tag name, but drop the empty class name? 59293 7 annevk 2011-10-31 14:14:55 +0000 Empty tags are dropped on the floor later on, but empty classes end up being stored. That will lead to questions about whether or not they can be matched against, etc. 59354 8 ian 2011-11-01 03:42:17 +0000 So your problem isn't really with <. per so, but with <anything. >? Ok. Fixed. 59358 9 contributor 2011-11-01 05:37:33 +0000 Checked in as WHATWG revision r6795.
