Intro

DescriptorExtension

A supporting term for the messages.

A Descriptor which extends another Descriptor.

Comments

Scope: DescriptorExtensions are Descriptors that extend a Descriptor. Example: Subtitle. A DescriptorExtension is not an AlternativeDescriptor because it cannot be used independently of the PrincipalDescriptor that it complements. Example: A Subtitle is not a complete Title on its own, and exists to extend or supplement a Title. Note that a DescriptorExtension is a DescriptorPart of an ExtendedDescriptor that is formed by concatenating the Descriptor and its DescriptorExtension.

Relationships
Parents	Descriptor	A Name or Annotation of an Entity expressed as a partially-defined or undefined data value.
Children	NameExtension	A Descriptor (such as a SubTitle) which is supplementary to, but not contained within, a Name.
