Defines a potential root node.
Connections.potentialRoot(A.R); Connections.potentialRoot(A.R, priority = p);
The overdetermined type or record instance
R in connector instance
A is a potential root node in a virtual connection graph with priority
p ≥ 0).
If no second argument is provided, the priority is zero.
p shall be a parameter expression of type Integer.
In a virtual connection subgraph without a Connections.root() definition, one of the potential roots with the lowest priority number is selected as root.
This definition may be used if in a model with connector
A the overdetermined record
A.R appears differentiated,
der(A.R), together with the constraint equations of
A.R, i.e., a non-redundant subset of
A.R maybe used as states.
