Michelle's recent message gives a usage for the default VLAN.

The structure of an untagged frame may imply membership of a specific VLAN;
e.g., for protocol-based VLANs, membership is implied by the  PDU's structure
being consistent with the reqirements of a given protocol.  This is rather
different from the "default" VLAN concept, which is about what you might do with
frames whose VLAN membership you cannot determine, or what you might do in order
to reach all members of all VLANs.
