an entry in a directory. DirectoryEntry is a mixin that identifies the attributes that must or may be present in any element that can be represented as an entry in a Directory.

a LocalURI that resolves to the full resource described by the DirectoryEntry. This should be present if the service either (a) supports the Read functional profile for the specified type or (b) is aware of another service that does.

a local identifier that names a unique resource within the context of type and the service context. This attribute must be present if the corresponding element has a local name. Note, however, that some elements (e.g. Association, ValueSetDefinition, etc.) do not local names and are identified exclusively by their href.

a relative measure of the "goodness of fit" of the directory entry within the context of the directoryFilter in the containing Directory.
