<remarks>

<p>Provides a means to segment the value space for the <code>type</code>, so that different organizations and individuals can assert control over the allowed <code>action</code>'s <code>type</code>. This allows the semantics associated with a given <code>type</code> to be defined on an organization-by-organization basis.</p>

<p>An organization MUST use a URI that they have control over. e.g., a domain registered to the organization in a URI, a registered uniform resource names (URN) namespace.</p>
