Specifies semantically the type of the attached document from a business perspective. The default classification scheme reuses the FIX standard classification scheme of a high level section (pretrade, trade, posttrade, etc.) and a category, then a specific application or document type. The expression follows {section/category/application type}.
The goal here is to map the attachment into the sections and categories of the FIX business messages if possible. The classification scheme can be expanded or replaced by counterparty agreement. This approach permits the introduction and reference to other business ontologies.
Example:
posttrade/confirmation/confirm
pretrade//termsheet
