A Feature defines a characteristic of the ModelElement that contains it. Specifically, Classifiers are defined largely by a composition of Features.

Attributes
Class	scope	The scope defines whether a Feature supports the definition of instances of the Classifier owning the Feature or of the Classifier as a whole. When scope is instanceLevel, the Feature is accessed through instances of the Feature's owning Classifier; when scope is classifier, the Feature is accessed through the Classifier itself (or through its instances). For StructuralFeatures, a scope of instanceLevel indicates that a value represented by the StructuralFeature is associated with each instance of the Classifier; a scope of classifierLevel indicates that the StructuralFeature value is shared by the Classifier and all its instances.
Class	visibility	In the future, this Attribute will be used to limit the ability of Elements outside of this Feature’s container to make use of it. The rules of visibility of MOF Elements are not currently specified.

public Class scope

The scope defines whether a Feature supports the definition of instances of the Classifier owning the Feature or of the Classifier as a whole. When scope is instanceLevel, the Feature is accessed through instances of the Feature's owning Classifier; when scope is classifier, the Feature is accessed through the Classifier itself (or through its instances). For StructuralFeatures, a scope of instanceLevel indicates that a value represented by the StructuralFeature is associated with each instance of the Classifier; a scope of classifierLevel indicates that the
StructuralFeature value is shared by the Classifier and all its instances.
