Hello.

I have a question about how UA client should utilize ContainsNoLoops attribute within View NodeClass.

I understand the meaning of the attribute, however I cannot imagine in which case the ContainsNoLoops attribute is to be used.

Please let me know the example where ContainsNoLoops attribute is used.

Best regards,

Toshi

The purpose of the Attribute was to allow the Server to publish a subset of the address space as a strict hierarchy. It was thought at the time that it would be useful to some clients. In practice, it may not be so useful.
