Extending wp_editor to include HTML5 data- attributes

I’m trying to use jqBootstrapValidation on my theme. It relies on being able to detect HTML5 validation elements on form elements, along with it’s own recognisable data API.
I need to have the wp_editor screen recognised as ‘required‘ and add a minlength attribute too; minlength="10"
Is there a way to programatically add this to thw wp_editor, or are there any other custom filters that I can be using to make this a little easier for myself?
Failing this, I think I’ll need to write some custom JS on the AJAX POST…

Any help would really be appreciated!
