SysMLv1.x: Limitation: The 'body' (maths formula) of an OpaqueBehavior can't be synchronised (shared) with the 'constraint' of a ConstraintBlock (directly in the SysML model). Can lead to a WET (not DRY) model and breaks Single Source of Truth!
The UML «Trace» and SysML Trace can't be applied to a Slot as target (because Slot is just an Element, not a NamedElement).

Allocate is directional in that one NamedElement is the "from" end (no arrow), and one NamedElement is the "to" end (the end with the arrow). Source OMG Systems Modeling Language (SysML) 1.6
Allocate is a stereotype of a UML4SysML::Abstraction that is permissible between any two NamedElements. It is depicted as a dependency with the "allocate" keyword attached to it. Source OMG Systems Modeling Language (SysML) 1.6
A Pseudostate is an abstraction that encompasses different types of transient Vertices in the StateMachine graph. A StateMachine instance never comes to rest in a Pseudostate, instead, it will exit and enter the Pseudostate within a single ... step Source Unified Modeling Language 2.5.1
