Yes, we can change the name of subobject. I read the minutes and guessed
George assumed an AI on this :)

>The point I forgot was to wonder whether there is a category of "best
>that follows most of the referenced LSP but not all hops?

Yes, current definition of inclusion (copying from draft) is:

0x02 = Best-effort inclusion
This flag is used to indicate that the route of the
LSP being signaled SHOULD follow the path
specified by the LSP subobject.

>Following that, what if there are specific hops in the referenced LSP
>that MUST
>be followed and others that only SHOULD be followed?

In this case the Ingress can divide the loose hop into two loose hops: one
with "lsp/ inclusion" subobject with mandatory inclusion and another one
with   "lsp/ inclusion" subobject with best-effort inclusion.
