           Summary: Require attributes on <embed> and data-* attributes to
                    be lowercase
           Product: HTML WG

            Status: NEW

For round-trippability and in order to avoid confusion with post-parsing
mutations of attributes (the U12345 stuff), attributes on <embed> and data-*
attributes should be required to be lowercase (in the ASCII range).

This would also give authors less rope when trying mixed case for data-*
attributes in text/html in markup and using the .dataset API.
