Description Ian 'Hixie' Hickson 2011-08-26 00:36:29 UTC 
This doesn't define the order of the array:
"The attributes attribute must return a read only array of the context object's associated attributes."
Comment 1 Ms2ger 2011-08-26 12:39:47 UTC 
The order in which they were added to the element. In particular, setAttribute/setAttributeNS say "*Append* this attribute to the context object's attributes."

I've tried to make this cleared by using "list of attributes" instead of "collection of attributes": <http://dvcs.w3.org/hg/domcore/rev/f1ac828a0830>.

I've filed bug 13917 to fix the "create an element for a token" definition in HTML, which doesn't define in what the order the attributes are added.
Comment 2 Ian 'Hixie' Hickson 2013-11-25 18:53:38 UTC 
Bug 13917 was WONTFIXed. Attributes in markup are conceptually unordered. If the API exposes an order, it's the API that should define the order, IMHO.
Comment 3 Anne 2013-11-26 13:05:59 UTC 
So if we have multiple disparate APIs they can all do their own thing? 

I think either we have a consistent order, we have a random order, or we have it implementation-defined and hope nobody starts depending on anything. I vastly prefer consistent order over the alternatives.
