CII-SR-248: Do not embed a logo for the seller in the invoice data

What it means

The seller must not have a LogoAssociatedSpecifiedBinaryFile element. That element stores a logo image inside the structured data of the invoice. EN 16931 has no field for a logo. The same restriction applies in the CII rules for XRechnung, NLCIUS and the French CTC rules.

Why it matters

This is a warning, so the file is still accepted. The recipient's software is not required to read or show the image, and it makes the file larger without adding anything the check can use. Fix it if you want a clean file, or if the recipient or a government e-invoicing portal limits file size.

How to fix it

Look in your invoicing software for an option such as include logo in the e-invoice or embed logo, and switch it off. The logo still appears on the invoice layout in the PDF, which is the right place for it. If you need to send a file with the invoice, add it as an attachment, because the standard has a separate place for those.
