Rationale/Explanation of issue:

In Section 4, the Table of Attributes states the following:

     The following table provides a guide to which attributes may be
     found in which kinds of packets, and in what quantity.

     Access- Access- Access- Access-   CoA-
     Request Accept  Reject  Challenge Req  #   Attribute
     0       0+      0       0         0+   TBD Egress-VLANID
     0       0-1     0       0         0-1  TBD Ingress-Filters
     0       0-1     0       0         0-1  TBD User-Priority-Table

The Egress-VLAN-Name attribute is not included in this table, nor is
it included in the IANA considerations section.

Section 2.1:

        Multiple Egress-VLANID attributes can be delivered in an
        authentication response; each attribute adds the specified VLAN
        to the list of allowed egress VLANs for the port.

This would appear to indicate that the Egress-VLAN-Name attribute is
allowed in Access-Challenge, Access-Reject and Access-Accept packets.
Yet, the attribute table in Section 4 does not seem to permit
inclusion in Reject or Challenge packets.

Section 2.3:

        Multiple Egress-VLAN-Name attributes can be delivered in an
        authentication response; each attribute adds the named VLAN to
        the list of allowed egress VLANs for the port.

This would appear to indicate that the Egress-VLAN-Name attribute is
allowed in Access-Challenge, Access-Reject and Access-Accept packets.
There is no entry in the Attribute Table to confirm this.

Section 2.4:

There is no material on permitted usage of the User-Priority-Table attribute.
