Description
The constructed initial system is wrong in certain cases:
msl32/Modelica.Fluid.Examples.AST_BatchPlant.BatchPlant_StandardWater.mos msl32/Modelica.Fluid.Examples.PumpingSystem.mos
Both examples produces the following output:
Notification: The given system is mixed-determined. [index > 0] Notification: The given system is mixed-determined. [index > 1] Notification: The given system is mixed-determined. [index > 2] Notification: The given system is mixed-determined. [index > 3] Warning: No system for the symbolic initialization was generated. A method using numerical algorithms will be used instead.
This means that the initial system is structural singular. I assume that there are a few implicit defined conditions missing.

- Milestone changed from Future to pre1.9.4
It doesn't make sense to keep closed ticket in the "Future" milestone that were simply forgotten to assign to the correct milestone in the past.

- Milestone changed from pre1.9.4 to 1.9.4
Removing the pre1.9.4 milestone in favor of 1.9.4.
Both models get now initialized (r24296).
