Detailed Description

Specifies constraints for a value. This allows explicit representation of path-sensitive properties. (Example: This value is always >= 0 on 1 if-branch then all users within that branch are rerouted to a confirm-node specifying this property).

A constraint is specified for the relation between value and bound. value is always returned. Note that this node does NOT check or assert the constraint, it merely specifies it.
