5j)     The term "unique" is used rather ambiguously in several places in the draft. Most of the time it is not specified on which level the uniqueness is required. An example: page 12 Section 4: "Each occurrence of the Host property should contain a unique value". Unique within a cluster, a site, a Grid or globally unique?
Evaluation: Needs clarification: Unique across what context? Be careful about scope of context.
