Identity Capability and Requirement Namespace.

 This class defines the names for the attributes and directives for this namespace. All unspecified capability attributes are of type String and are used as arbitrary matching attributes for the capability. The values associated with the specified directive and attribute keys are of type String, unless otherwise indicated. 

Each resource provides exactly one† identity capability that
can be used to identify the resource.


The bundle wiring for the bundle revision provides exactly
one† identity capability.


† A resource with no symbolic name must not provide an identity
capability.
