[Nsi-wg] Some comments for latest service definitions

[Henrik Thostrup Jensen]

Hi

In revision 101 label got re-added under StpType, which fits with what we 
agreed with on the call as far as I can remember. However sourceVLAN and 
destVLAN still exists in the EthernetVlanType. Is there a reason for this, 
or did we just forgot to take them out.

Further is there a reason to keep EthernetVlanType around? If one wants a 
VLAN, one just specifies a label and if one wants plain ethernet, no label 
should be specified (right?).

We also have some discrepency between NML and STPs. A Port/PortGroup in 
NML can only have a single label, which has a single value. Our StpType 
can have multiple labels. Furthermore a label can have multiple values, 
which confuses me a bit, but it might be related to the next issue.

Overqualifying labels is something that isn't really documented anywhere 
AFAICT. In NML we specify ranges with "start-end" and AFAIK, can also be 
comma-seperated. In NSI I reckon we should do the same when 
overqualifying, and only have a single value in the label. Furthermore we 
should have it written down... somewhere... how to overqualify a label 
with the "start-end" semantics.


     Best regards, Henrik
