Clause 6.4 is the detailed description. Its subclauses cover general rules, relationships between classes, attributes of classes, generalised classes and patterns, and translation and language. Read together, they describe a model in which objects are connected by explicit relationships, attributes carry the data elements, patterns are reused rather than invented for each product type, and language is handled as a property rather than by duplicating the object. The public contents give the titles but not the diagrams. The exact cardinalities, the attribute names and the translation rules are not stated in the text we hold. The value of the clause for a non-implementer is the shape it imposes: a relationship is a first-class thing, so a package component is not a text field on a product, and a translation is not a second product.
