39 The <org root> portion of the UID uniquely identifies an organization, (i.e., manufacturer, research
40 organization, NEMA, etc.), and is composed of a number of numeric components as defined by ISO 8824.
41 The <suffix> portion of the UID is also composed of a number of numeric components, and shall be
42 unique within the scope of the <org root>. This implies that the organization identified in the <org root> is
43 responsible for guaranteeing <suffix> uniqueness by providing registration policies. These policies shall
44 guarantee <suffix> uniqueness for all UID's created by that organization. Unlike the <org root>, which may
45 be common for UID's in an organization, the <suffix> shall take different unique values between different
46 UID's that identify different objects.
