This document discusses principles for designing mechanisms that use
or provide path signals and calls for standards action in specific
valuable cases.  RFC 8558 describes path signals as messages to or
from on-path elements and points out that visible information will be
used whether or not it is intended as a signal. The principles in
this document are intended as guidance for the design of explicit
path signals, which are encouraged to be authenticated and include a
minimal set of parties to minimize information sharing. These
principles can be achieved through mechanisms like encryption of
information and establishing trust relationships between entities on
a path.
