XHTML / SyntaxError: An invalid or illegal string was specified

[vinkl]

Line 257 should be as follows to work with XTHML:

$checkRequired = $('<input required="required"/>'),

instead of

$checkRequired = $('<input required="required">'),

Otherwise, when used with JQuery, it will cause:

SyntaxError: An invalid or illegal string was specified
tmp.innerHTML = wrap[1] + elem.replace( rxhtmlTag, "<$1></$2>" ) + wrap[2];

Thanks for the report.

If you'd like to create a pull request and make sure all the tests still pass, that would be useful.

Just a warning about XHTML or XHTML5 -- IE has never properly handled XML mime-types until IE9 -- so if you need legacy IE support, I strongly recommend that you do not use XHTML unless you have a good content negotiation strategy in place on the server so you can serve HTML5 to old IE.
