UML22 — Clarification of Information Flow semantics

Description: Consider the following recommendations to improve Information
Flow semantics:
b) Allow Information Flow to be specialized and decomposed using
aggregation.
c) Allow Information Flow between classifiers with ports and interfaces.
Make provisions for relating the information flow to a port, such that an
Information Flow can flow through a port.
d) Allow Information Flows between classifiers with object flows across
activity partitions.
e) Change the name from Information Flow to Item Flow (or something similar)
to allow for the flow of non-information, such as physical items specified
in systems engineering applications.
