RE: [ubl-ndrsc] Recursive container?

["A Gregory" <agregory@aeon-llc.com>]

Folks:

My understanding is exactly what Eduardo just described. There should
never be a case where a list of list containers will need a container,
since according to our rules it would only ever produce a single list.

Cheers,

Arofan

What I mean is that UBLContainer is just a shorthand description of
something
else.

THere would never be something like:

<BuyerPartyType>
     <UBLContainer>
         <PartyName> <!-- 0..n --> </PartyName>
         <PartyName> <!-- 0..n --> </PartyName>
     </UBLContainer>
     <UBLContainer>
         <Address> <!-- 0..n --> </Address>
         <Address> <!-- 0..n --> </Address>
         <Address> <!-- 0..n --> </Address>
     </UBLContainer>
</BuyerPartyType>

What you will encounter will be:

<BuyerPartyType>
     <PartyNameList>
         <PartyName> <!-- 0..n --> </PartyName>
         <PartyName> <!-- 0..n --> </PartyName>
     </PartyNameList>
     <AddressList>
         <Address> <!-- 0..n --> </Address>
         <Address> <!-- 0..n --> </Address>
         <Address> <!-- 0..n --> </Address>
     </AddressList>
</BuyerPartyType>

There would be no common container to contain, would there? I never
thought
at any time that someone was proposing UBLContainer as a real element
name
for generic use whenever there was a need for a container. If I had I
would
have opposed it quite vocally ;)

(BTW, I still remain unconvinced that 0..n elements need containers, so
I'm using this particular example only because you used it, not because
I believe it's a good one...)
