The definitions "LSP tunnel" in the docs
seem to be somewhat misleading. For example,
section 3.27.3 of RFC 3031 states:

"It is possible to implement a tunnel as a
LSP, and use label switching rather than
network layer encapsulation to cause the
packet to travel through the tunnel. ...
This is called a "LSP Tunnel."

This is standard MPLS as far as I tell.
Why rename it?

Also, section 1 of draft-ietf-mpls-rsvp-lsp-tunnel-08.txt
states:

"Since the traffic that flows along a label-switched path is defined
by the label applied at the ingress node of the LSP, these paths can
be treated as tunnels, tunneling below normal IP routing and
filtering mechanisms.  When an LSP is used in this way we refer to it
as an LSP tunnel."
