Description

In the canonical UML, 61970 PowerSystemResource child classes inherit an association to AssetInfo. This means that, as a child of PowerSystemResource, the TransformerTank class has an allowed association to classes as diverse (and illogical) as EndDeviceInfo, SurgeArresterInfo and WireInfo. This situation forces 61970 profiles to articulate constraints that are actually universal and not profile-specific.

Proposed Solution

Add an explicit association between TransformerTank and TransformerTankInfo.


Release Notes

Add association TransformerTankInfo.TransformerTank, ensuring that the association source is TransformerTankInfo and the target is TransformerTank since the association ‘spans’ the 61968/61970 package divide.
