JAR PPL revalidation question?

[TangoZulu]

I recently revalidated my PPL by the experience route i.e. 12 hours or which at least 6 were P1, in addition to a one hour flight with an examiner (IMC flight test).

I then got the examiner to sign it before the expiry date in the licence - all well and good me thinks.

I then discover that there is a form which should have been filled in, signed by me and the examiner and sent off the the CAA - no mention of this by the examiner who signed off the revalidation.

I now have said form and wonder if this is just a paperwork exercise, or whether there is more to it than just filling the form in now, getting the examiner to sign and sending it off to the CAA.

Apologies if this seems like a stupid question but I just want to confirm that the revalidation is valid by the signature in my licence?

Thanks
