Subject: For ldp if loop detection is disabled must the LSR still check for loops?

LDP Clarifications needed:

The ldp spec (rfc3036) appears to require the LSR
to detect loops (send a loop detected Notification
message) even if loop detection is disabled.

If loop detection is enabled, the ldp spec (rfc3036)
requires that the LSR include Hop Count and Path Vector
TLVs in Label Request and Label Mapping messages,
in addition to requiring that the LST to detect loops.

Is this interpretation correct?

If so than an LSR with loop detection disabled will always
send a loop detected Notification message when it receives
a Label Request that contains a Path Vector TLV with at least one
LSRID.
