[UML-2.5.1] InstanceSpecification::classifer : Classifier [0..*] ... The Classifier or Classifiers of the represented instance. If multiple Classifiers are specified, the instance is classified by all of them. [UML-2.5.1] InstanceSpecification::slot : Slot [0..*] ... A Slot giving the value or values of a StructuralFeature of the instance. An InstanceSpecification can have one Slot per StructuralFeature of its Classifiers, including inherited features. ... [UML-2.5.1] InstanceSpecification::slot : Slot [0..*] ... It is not necessary to model a Slot for every StructuralFeature, in which case the InstanceSpecification is a partial description. [SysML-1.6] A Slot designates that an entity modeled by an InstanceSpecification has a value or values for a specific StructuralFeature. [UML-2.5.1] Slot::definingFeature : StructuralFeature [1..1] ... The StructuralFeature that specifies the values that may be held by the Slot. [UML-2.5.1] Slot::owningInstance : InstanceSpecification [1..1] ... The InstanceSpecification that owns this Slot. [UML-2.5.1] Slot::value : ValueSpecification [0..*]{ordered, subsets Element::ownedElement} ... The value or values held by the Slot.

Object diagrams are great for exploring Slot values, too. UML/SysML: MagicDraw/Cameo: Instance Table Diagrams are one of the most powerful features of MagicDraw/Cameo! Learn to use them to progressively test, debug, and evolve your models as you work!
