However, those are within the scope of "Diff-Serv-aware MPLS Traffic Engineering" (DS-TE) developed in the TEWG. In RFC3564 "Requirements for Support of Differentiated Services-aware MPLS Traffic Engineering", you may be interested in section "1.3 Mapping of traffic to LSPs" which discusses the options of how "classes of services" may be split/grouped over L-LSPs/E-LSPs.
