The use counters for the setter are a bit too high, even if only counting when actually attached to an element.

Also need to add Attr.prototype.textContent as alias per http://www.chromestatus.com/metrics/feature/timeline/popularity/349
Comment 2 Philip Jägenstedt 2014-08-18 14:06:40 UTC 
First I think we should determine if making Attr not inherit Node and not have child nodes is going to fly. Unfortunately there are lots of APIs that expose the fact that Attr is a Node and has children, at least:

childNodes
firstChild
lastChild
insertBefore
replaceChild
removeChild
appendChild
hasChildNodes
cloneNode
normalize
contains

... and probably more. The best I can think of is to try to separate these into buckets AttrChildNodeAccess and AttrChildNodeModification and see if usage is low enough. Am I missing something?
Comment 3 Anne 2014-08-18 14:13:52 UTC 
That seems correct. Whether Attr needs to be a Node we should probably track separately from whether Attr should have a settable value and textContent though. Would be really sad if that was required.
