Subject: Fix #11547. toLowerCase not work good on XML attributes.
X-Git-Tag: 1.8rc1~47
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=f4e5c1729a2efe6086ac2407f82e928b26991f83;p=jquery.git

Fix #11547. toLowerCase not work good on XML attributes.

This was fixed to some extent in gh-724 but there were insufficient test cases. Removing the lowercase completely allows IE 6/7 to work properly since there you need an exact case match for attributes, even in HTML docs. More discussion and test cases in the comments on gh-724.
