=== Template !FlangeConnection ===

[[br]]This template is for describing a flange connection of 2 Individuals.
[[br]]
[[br]]!FlangeConnection(a, b, c, d) means that a and b are (temporal parts of) !PossibleIndividual that are connected indirectly through a gasket of type c and a set of bolts of type d.

=== Comments ===
Classes of relationships !ComponentHasPort, !PortConnectsToPort, !UsedGasket and !UsedBolt should already exist in RDL.
!AggregateOfBolts should be modelled separately according to Hans's diagram: http://www.15926.info/aggregate-of-individual/index.htm
