The name of the trigger glyph is potentially misleading. The current semantics are that a process attached to a modulating condition is satisfied. This is not what is suggested by a trigger, which implies that it will stimulate something to happen, but that the process could porentially occur without the trigger. To clarify this we propose (AS,FS,NL,SM) that this be renamed as "Necessary Stimulation" to better imply the correct semantics of the glyph.
Removed. May need proof reading.
