UI Date Picker v3.4.3 fails in Safari 3.1.1 for Windows

When a document is served as application/xhtml+xml, innerHTML doesn't work, and Safari throws a fit.

Passing well-formed markup into jQuery on line 99 eliminates the need for innerHTML when creating the singleton DIV, and the datepicker works.

Line 99 should read:

this._datepickerDiv = $('<div id="datepicker_div"></div>');
