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.

NOTE 2
See Annex D,
Figure
D.1
for a graphical representation of this schema.
This subclause specifies the MIM rule for
this module. The MIM rule and definition is
specified below.
The text_font_usage rule ensures that every instance of externally_defined_text_font
and of pre_defined_text_font
is referred to by at least an instance of text_literal, of which it specifies the font.
EXPRESS specification:
*)
RULE text_font_usage FOR
(externally_defined_text_font, pre_defined_text_font);
WHERE
WR1: SIZEOF (QUERY (pdtf <* pre_defined_text_font | SIZEOF (USEDIN (pdtf, 'PRESENTATION_DEFINITION_SCHEMA.TEXT_LITERAL.FONT'))
= 0 )) = 0;
WR2: SIZEOF (QUERY (edtf <* externally_defined_text_font | SIZEOF (USEDIN (edtf, 'PRESENTATION_DEFINITION_SCHEMA.TEXT_LITERAL.FONT'))
= 0 )) = 0;
END_RULE;
(*
Argument definitions:
externally_defined_text_font :
the set of all instances of
externally_defined_text_font.
pre_defined_text_font :
the set of all instances of
pre_defined_text_font.
Formal propositions:
WR1:
There shall not be any instance of externally_defined_text_font
that is not referred to by any instance of text_literal.
WR2:
There shall not be any instance of pre_defined_text_font
that is not referred to by any instance of text_literal.
