I second this request.
I've seen some other developers stop using the rel="" attribute and switch to a data="" attribute. For example, the Lightbox Plus plugin was using rel="lightbox[post_id]" until recently. The developer was able to change that to data-lightbox="[post_id]" to maintain functionality and validate under html5.
I'd propose offering data-faq="" instead of rel="" for all instances.
I would appreciate it if you would offer that as an option so my FAQ pages can validate. Thanks! Please let me know if you need more information from me.
