Next snippet A part or value property is always shown on an internal block diagram with a solid-outline box. Related snippets SysML establishes four basic classifications of properties belonging to a SysML Block or ValueType. A property typed by a SysML Block that has composite aggregation is classified as a part property, except for the special case of a constraint property ... Constraint properties are further defined in Clause 10. A port is another category of property, as further defined in Section 9. A property typed by a Block that does not have composite aggregation is classified as a reference property. A property typed by a SysML ValueType is classified as a value property, and always has composite aggregation.
