A question about the name prefixes in section 2.3.3 of the CDL specification

Dear Colleagues,
 
 
  An editing question: in section 2.3.3 

<roleType name="Buyer">

   . . .

</roleType>

<roleType name="SellerForBuyer">

    <behavior name="sellerForBuyer" interface="rns:sellerForBuyerPT"/>

</roleType>

<roleType name="SellerForShipper">

    <behavior name="sellerForShipper" interface="rns:sellerForShipperPT"/>

</roleType>

<roleType name="Shipper">

   . . .

</roleType>

<relationshipType name="Buyer-Seller">

    <role type="tns:Buyer" />

    <role type="tns:SellerForBuyer" />

</relationshipType>

<relationshipType name="Seller-Shipper">

    <role type="tns:SellerForShipper" />

    <role type="tns:Shipper" />

</relationshipType>

 

<participantType name="Broker">

   <role type="tns:SellerForBuyer" />

   <role type="tns:SellerForShipper" />

</participantType>

 
should the two rns: name prefixes be tns: or are they deliberately
different?
