Steps to reproduce:
1. Point URL or cut and paste watch.html into html validator tool of choice (Oxygen, http://htmlhelp.com/tools/validator, validator.w3.org, etc)
2. Note the issues in red
Actual Results: issues are reported
Expected Results: Valid document, or passes most validation checks.
Workaround (if any): Watch.html sees to function ok currently in most browsers. There is potential for some browsers to be thrown into quirks mode by the errors. Browser behavior cannot be predicted over invalid html.
