This clause specifies the EXPRESS schema derived from the mapping
table.
It uses elements from the common resources or from other application
modules and defines the EXPRESS constructs that are specific to this
part of ISO 10303.
This clause constitutes the Module Interpreted Module (MIM) of the
application module.
This clause also
specifies the modifications that apply to the constructs
imported from the common resources.
The following restrictions apply to the use, in this schema, of constructs defined in common resources or in application
modules:
-
use of a supertype entity does not make applicable any of its
specializations, unless the specialization is also imported in the
MIM schema;
-
use of a SELECT type does not make applicable any of its listed types
unless the listed type is also imported in the MIM schema.
Short names of entities defined in this schema are described in Annex A. Unambiguous identification of this schema is defined
in Annex B.

This subclause specifies the MIM subtype constraint for
this module. The subtype constraint places a constraint on the
possible super-type / subtype instantiations.
The MIM subtype constraint and definition is
specified below.
A multi_stratum_structured_template_subtypes constraint specifies a constraint that applies to instances of subtypes of
multi_stratum_structured_template.
