4431,Change the jQuery expando prefix to data-jquery,dantman,,"http://www.whatwg.org/specs/web-apps/current-work/#custom-data-attribute
HTML 5 defines a specific pattern for custom data on nodes. Seams like the best idea to make use of that standard for defining the jQuery expando.

To fit that standard, this line:
var expando = ""jQuery"" + now(), uuid = 0, windowData = {};
Would change to:
var expando = ""data-jquery"" + now(), uuid = 0, windowData = {};",enhancement,closed,low,,data,1.3.2,invalid,,,,
