WR2: If auxiliary_shape_representations is provided then primary_shape_representation shall be provided.

4.3.5 View_definition_context   EXPRESS-GMapping table

A View_definition_context is the grouping of an application domain and a life-cycle stage. It identifies a universe of discourse suitable for the description of products.

A View_definition_context is either an Additional_view_definition_context or an Initial_view_definition_context in which the application domains are specified.

EXPRESS specification:

*)
ENTITY View_definition_context

  description : OPTIONAL STRING;
END_ENTITY;
(*

Attribute definitions:

life_cycle_stage: the text that identifies a stage in the life cycle of a product.

EXAMPLE    'design phase', 'production', 'recycling phase' are life-cycle stages.

If life_cycle_stage is an empty string, the View_definition_context shall be considered as not specific of any life-cycle stage.

description: the text that provides further information about the View_definition_context. The value of this attribute need not be specified.
