UML/SysML: MagicDraw/Cameo: WARNING: If you assign a value to a Slot for an untyped Property then assign a ValueType later it will DELETE your assigned value! Assign a type first .
For example, a block that represents the definition of a wheel can be used in different ways. The front wheel and rear wheel can represent different usages of the same wheel definition. Source OMG Systems Modeling Language (SysML) 1.6
A part belonging to a block, for example, may be typed by another block. The part defines a local usage of its defining block within the specific context to which the part belongs. Source OMG Systems Modeling Language (SysML) 1.6
A property can represent a role or usage in the context of its enclosing block. A property has a type that supplies its definition. Source OMG Systems Modeling Language (SysML) 1.6
Webel has a proposal for clearly revealing anonymous typed elements in SysML callouts and on derived Properties from operation queries.
If you are using Blocks (not InterfaceBlocks) to Type your Ports just use "manual" feature-by feature direction inversion to achieve type conjugation (and you can even use a ~ tilde prefix)
SysML: Typing a Port by an InterfaceBlock or ~InterfaceBlock does NOT imply that the Port is a ProxyPort (but ProxyPort must be typed by an InterfaceBlock or ~InterfaceBlock)

Null tokens (object tokens without a value) satisfy the type of all object nodes. Source Unified Modeling Language 2.5.1
ObjectNodes are TypedElements ... If an ObjectNode has a type specified, then any object tokens held by the ObjectNode shall have values that conform to the type of the ObjectNode. If no type is specified, then the values may be of any type. Source Unified Modeling Language 2.5.1
