This section describes the extent and limits of the business processes within the supply chain being described in this document. Each industry may specify, based on the BRS of the cross industry catalogue processes, its industry specific use of the catalogue message and the business processes. It also allows for industry specific functionality on details to describe a specific product. Name/Value pairs in the catalogue documents allows the Catalogue Provider to add attributes to further specify their products in the existing structure. If further elaboration is needed an industryspecific ontology can be made. Industry specific ontology is outside the scope of this BRS
