Motivated by these observations, XML.org would like to assign URNs to some resources in order to retain unique, permanent location-independent names for them. This namespace specification is for a formal namespace. Assignment is limited to the owner and those authorities that are specifically designated by the owner. In addition, the owner may provide an online resolution service based on RFC2483. The owner will authorize additional resolution services as appropriate.
URNs are lexically equivalent if they are lexically identical.
The presence of a URN in a catalog indicates that it is valid. The following examples are not guaranteed to be real. They are listed for pedagogical reasons only. There are no additional security considerations other than those normally associated with the use and resolution of URNs in general. All Rights Reserved.
