Table B.1. Types of Variation Points

Type of variation point	Definition	Example
Dimension	Feature (or concept) of which all direct subfeatures (or features) are alternative features.
Dimension with optional features	Feature (or concept) of which all direct subfeatures (or features) are alternative optional features.
Extension point	Feature (or concept) that has at least one direct optional subfeature (or feature) or at least one set of direct or-subfeatures (or or-features).
Extension point with optional features	Feature (or concept) of which all direct subfeatures (or features) are optional features.
Extension point with or-features	Feature (or concept) of which all direct subfeatures (or features) are or-features.
