BR-DE-7: seller email address missing

The seller contact (BG-6) needs an email address (BT-43). A related rule, BR-DE-28, warns when the value does not look like a normal email address.

What the validator reports

BR-DE-7: Das Element "Seller contact email address" (BT-43) muss übermittelt werden.

This is the message our validator returns for an invoice with this problem. The text is the official rule text.

The official XRechnung rule texts are published in German, so the message is in German.

Fill in a valid email address in the seller contact.
