Product Add-Ons

Add-ons don’t do any sort of JS validation (yet) before allowing a product with add-ons to be added in the cart.

However, since the extension is deeply integrated in others that **must** validate user input in the front-end (eg composite products), it would be nice to have at least something 3rd party devs can use to know when an Add-ons input field has valid data or not, even at a very basic level (ie only to ensure that the user has made a selection, without any sort of content validation such as max char count, etc).
