ISO 15511 (ISIL) accommodates country and non-country based identifiers. Each country has or will have a national authority that assigns identifiers within its borders, and this authority is required to register with the Danish National Library (DNL), the official registration authority for ISIL. Non-country identifiers can be assigned by organizations that work with repositories internationally, though the prefix used to identify such identifiers must be registered with the DNL. ocl as a non-country prefix is given as an example for OCLC (http://www.bs.dk/isil/structure.htm), though I did hear last fall that OCLC had not yet formally registered "ocl" with the DNL.
