CII Missing check on DefinedTradeContact cardinality

[AndreasPvd]

Hello all,

The EN16931 defines that BG-6 (Seller contact) and BG-9 (Buyer contact) have a cardinality of 0..1. UBL matches this definition as it only provides one contact per party. But CII supports multiple contacts (0..n).
The check to prevent the provision of multiple BG-6 and BG-9 is missing in the validation artefacts.

Between CII-SR-226 and CII-SR-227 there should be a rule added like
<param name="CII-SR-XXX" value="( count(ram:SellerTradeParty/ram:DefinedTradeContact) &lt;= 1)"/>

and between CII-SR-255 and CII-SR-256 there should be a rule added like
<param name="CII-SR-YYY" value="( count(ram:BuyerTradeParty/ram:DefinedTradeContact) &lt;= 1)"/>

and definitely the corresponding messages

<assert test="$CII-SR-XXX" flag="fatal" id="CII-SR-XXX">[CII-SR-XXX] - DefinedTradeContact of SellerTradeParty should exist maximum once</assert>
<assert test="$CII-SR-YYY" flag="fatal" id="CII-SR-YYY">[CII-SR-YYY] - DefinedTradeContact of BuyerTradeParty should exist maximum once</assert>

Br,
Andreas
