Dave,

Mechanisms to support multiple class types on an E-LSP were proposed
in this WG. Some providers and vendors expressed interest in 
such schemes. However, in Utah, the WG felt that standardizing
multiple OA-ELSP would be premature until the basic DS-TE
mechanisms are standardized and shown to be viably deployable.

Updated versions of the related drafts can be found below:

Best,
Nabil Seddigh
