Re: [ubl-dev] infinite loop

There is a required business rule that the cardinality at some level of the loop must be optional. If the loop does not contain that restriction then there is an issue with either the data model or schema.

Subject: [ubl-dev] infinite loop

Hi,
I' m working on UBL xsd files to obtain a tree viewer of the documents,but the algorithm enter into an infinite loop because of the structure of the xsd.
For example, in the Order document there is the element "Signature" of type: Signature type. Signature type,that is a complex type, contains the element "SignatoryParty" of type PartyType. PartyType, that is a complexType, contains AgentParty that is a PartyType and will contain another AgentParty element...and so on.
Is it true? I don't understand the meaning of these circular calls.
