I talked myself through this:

PortGroup == VLAN range in LabelGroup
Port == Single VLAN Label

Therefore, the ampath and nordunet topologies are generated incorrectly as they are mixing up definitions.

I thought Label is a single value, so they vlan range cannot be specified in there.  If it was a single port with one vlan then it might be viable, however, using a vlan range in the label file is semantically incorrect.

The same goes for the unidirectional port declarations, some use Port and Label:

      <nml:Port id="urn:ogf:network:nordu.net:2013:netherlight-out">
        <nml:Label labeltype="http://schemas.ogf.org/nml/2013/05/ethernet#vlan">1780-1783</nml:Label>
        <nml:Relation type="http://schemas.ogf.org/nml/2013/05/base#isAlias">
          <nml:Port id="urn:ogf:network:netherlight.net:2013:port:a-gole:testbed:nordu.net:1:in"/>
        </nml:Relation>
      </nml:Port>

While others use PortGroup and LabelGroup:

      <nml:PortGroup id="urn:ogf:network:netherlight.net:2013:port:a-gole:testbed:nordu.net:1:out">
        <nml:LabelGroup labeltype="http://schemas.ogf.org/nml/2012/10/ethernet#vlan">1779-1799</nml:LabelGroup>
        <nml:Relation type="http://schemas.ogf.org/nml/2013/05/base#isAlias">
          <nml:PortGroup id="urn:ogf:network:nordu.net:2013:netherlight-in"/>
        </nml:Relation>
      </nml:PortGroup>

Can both ways be used?

            <nml:PortGroup id="urn:ogf:network:netherlight.net:2013:port:a-gole:testbed:232:out"/>
        </nml:BidirectionalPort>

or

        <nml:BidirectionalPort id="urn:ogf:network:ampath.net:2013:ndn">
            <nml:name>ndn</nml:name>
            <nml:Port id="urn:ogf:network:ampath.net:2013:ndn-in"/>
            <nml:Port id="urn:ogf:network:ampath.net:2013:ndn-out"/>
        </nml:BidirectionalPort>

Should Port or PortGroup be used?  We have a mix right now in our topologies.

Thanks,
John
