What it means
The rule counts direct ram:URIUniversalCommunication children of each ram:ManufacturerTradeParty under the line's ram:SpecifiedTradeProduct. Zero or one passes; two or more fail. It does not check the block's contents or count contact email blocks under ram:DefinedTradeContact.
Why it matters
The manufacturer entry has one optional URI communication block. Communication details within a contact are separate fields.
How to fix it
Check ram:URIUniversalCommunication directly inside the affected ram:ManufacturerTradeParty. Keep the intended block and remove any additional copies. If no electronic address entry is needed, you can omit it. Save or export the corrected file and check it again.
