The document states:

"The L2SC Interface Switching Capabilities MUST NOT be used to represent
interfaces capable of supporting Eth-LSPs. Interface Switching
Capability specific TE information may be defined as needed to support
the requirements of a specific Ethernet Switching Service Type."

[...]

"It is expected that there will be no case where an Eth-LSP will be
signaled, or an Eth-LSP supporting interface will be represented, using
the L2SC switching type/capability. A new switching type/capability is
required to avoid any potential current usage of the L2SC switching
type/capability in support of Ethernet."

This is explicit statement that GMPLS per RFC 3945 is not applicable.
So, it is much more than just an additional codepoint, as the control
plane behaviour is to be defined for this codepoint. So, it is the open
door for a new control plane behaviour. 

so, let's have a more basic questioning before jumping into the single
alternative resulting from this doc.:

- either it is GMPLS for Ethernet architecture and then what exist in
current RFCs should be applicable (because i do not see any rationale
for L2SC def. departure for Ethernet frame processing);

- or not it is X for Y architecture, where X is an IP control protocol
based some potentially on some existing GMPLS blocks and Y is not
compatible with the existing definition of Eth frame processing.

In the latter case, i do not know how this WG can deal with such case
(from the control plane perspective).
