MidTmcLeafNodeCspSubarray Specific Attributes
=============================================

No additional attributes are defined in the MID-specific class
(`MidTmcLeafNodeCspSubarray`) beyond those inherited from the base class.

The main difference is in delay model calculation parameters (properties) and behaviour.
