Acee,

Agree with you that the interpretation should be that the node tags for certain router is  the super set of all the tags from all node-admin tag TLVs from all instances of RI LSA advertised by that router.
Will update the document.

Authors, 

In the “Elements of Procedure” section, please address how multiple instances of the TLV will be handled. At a minimum, the following cases must be handled:

     1. Multiple instances of the TLV in the same OSPF(v3) Router Information LSA
     2. Multiple instances of the TLV in multiple OSPF(v3) Router Information LSA instances
     3. Removal an instance of the TLV in an OSPF(v3) Router Information LSA through re-origination
     4. Purge of an OSPF(v3) Router Information LSA containing the node admin tags TLV. 

One possible interpretation (and probably the simplest) is that the set of valid tags for a given OSPF(v3) router is the superset of the tags in all the existing OSPF(v3) Router Information LSAs advertised by that router.

Thanks,
Acee
