Hi Tim,

Can we try and reach agreement on this issue?

Table 4: is about primary elements. So no change required here.

Should we consider Table 4(bis), which is about secondary elements.
In a first approximation, it would contain the following entries:

wasStartedBy: Activity x Activity (starter)
wasEndedBy: Activity x Activity (ender)
wasDerivedFrom: Entity x Activity
mentionOf: Entity x Entity(Bundle)
wasAssociatedWith: Acivity x Entity (Plan)
actedOnBehalfOf: Agent x Activity


Figure 5 contains the required associated ender/starter from the 
association classes.

Cheers,
Luc
