SYSMLR — Incorrect statement about UML n-aries

Section 8.3.1.3 (UML Diagram Elements
not Included in SysML Block Definition
Diagrams) says "N-ary associations,
shown in UML by a large open diamond
with multiple branches, can be modeled
by an intermediate block with no loss in
expressive power." An intermediate
block cannot capture multiplicities that
would be on an the ends of an n-ary
association. These multiplicities are
for the links from end to end, rather
than from intermediate object to end, as
they would be with an intermediate
object. However, intermediate blocks
can specify the number of links each end
might participate in for any of the
other n-1 ends, which is not possible
with n-ary associations. The
expressiveness of n-aries and
intermediate blocks is overlapping,
rather than equivalent.
