Terms and conditions as PDF attachment to confirmation email
We have an issue with one of our shop certificates, the Danish "E-Mærket" certification (https://www.emaerket.dk), requiring that the terms and conditions accepted during checkout is also send attached as a pdf file with the confirmation email sent to the customer, therefor we would like to add an attachment feature for the confirmation email in order to maintain our certification.
This function could be used for other things as well.

I agree with this suggestion but would also like to propose that it be enhanced with a feature to make an MD5 hash (or similar cryptographic hash) of the terms and conditions + the details of the order. Then there can be no dispute about either the terms and conditions or what was ordered.
