I recently upgraded jquery from Jquery.ui.1.7.2.js, jquery1.3.2.js to jquery-ui-1.9.2.js
jquery-1.8.3.js.

We use MVC and have a lot of name attributes with period in them so they get put into our models.

Code that used to work no longer works because jquery no longer allowed periods in name value selectors.

On the following page

http://api.jquery.com/attribute-equals-selector/

it says

value: An attribute value. Can be either an unquoted single word or a quoted string.

So can someone specifically tell me what constitutes a single word? It seems underscores can be used in a single word? What characters are allowed and aren't allowed in selector values?
