Resources may exist at various hierarchy domains (levels) within an Interchange Data Stream. Each level is defined such that the applicability scope of document resources for a given level is valid for all referencing entities existing within a particular level and for all higher level(s). Thus, common resource definitions may exist at higher document levels, maximizing the degree of resource sharing while exclusive resource definitions can be defined within a particular document hierarchy domain. Note that the lifetime of resources is determined by the lifetime of a particular document hierarchy domain (e.g., Document, Page, Data Object).
