Subject: IE doesn't like doing attaching the mergeNum property to XML documents, so for now... 
X-Git-Url: http://git.asbjorn.biz/?a=commitdiff_plain;h=3604d14896568ecdaaa232dc12380a56fa7c4b0c;p=jquery.git

IE doesn't like doing attaching the mergeNum property to XML documents, so for now, we're just going to (possibly) return duplicates in IE, in XML documents. (bug #1357).
