An UNRESOLVED response lists the components of the name that must be further resolved relative to the immediately preceding LINK response or responses, and is used when not all components of a multiple-component name were resolved.
The name-components must be a proper suffix of the name-components sent as an argument to the LIST command. For instance, to the command
LIST '' COMPONENTS ulink-test2 murali ROOT
the only two legal UNRESOLVED responses are
UNRESOLVED murali ROOT
