connection_area: specifies the role of the Connection_zone_in_layout_template for the Via_template_terminal. There may be one or more Connection_zone_in_layout_template for the Via_template_terminal. The value of this attribute need not be specified. If the data is available in the source system, the data shall be provided.

Formal propositions:

UR1: The combination of the element_name and associated_definition shall be unique within a population of Via_template_terminal.

WR1: The description shall not be populated.

4.4 ARM subtype constraint definitions

This subclause specifies the ARM subtype constraints for this module. Each subtype constraint places constraints on the possible super-type / subtype instantiations. The ARM subtype constraints and definitions are specified below.

4.4.1 list_template_definition_subtypes   

The list_template_definition_subtypes constraint specifies a constraint that applies to instances of Template_definition and enforces the rule that its subtypes Geometric_template, Parametric_template, Part_string_template, Part_text_template, Single_stratum_template and Stratum_stack_model are exclusive.

EXPRESS specification:

*)
SUBTYPE_CONSTRAINT list_template_definition_subtypes FOR Template_definition;
  ONEOF (Geometric_template,
         Parametric_template,
         Part_string_template,
         Part_text_template,
         Single_stratum_template,
         Stratum_stack_model);
END_SUBTYPE_CONSTRAINT;
(*

4.4.2 list_shape_feature_subtypes   

The list_shape_feature_subtypes constraint specifies a constraint that applies to instances of General_part_feature and enforces the rule that its subtypes Via_template_terminal, Component_termination_passage_template_terminal and Land_template_terminal are exclusive.

EXPRESS specification:

*)
SUBTYPE_CONSTRAINT list_shape_feature_subtypes FOR General_part_feature;
  ONEOF (Via_template_terminal,
         Component_termination_passage_template_terminal,
         Land_template_terminal);
END_SUBTYPE_CONSTRAINT;
(*

4.4.3 lisp_shape_element_subtypes   

The lisp_shape_element_subtypes constraint specifies a constraint that applies to instances of Shape_element and enforces the rule that its subtypes Non_feature_shape_element and Edge_segment_vertex are exclusive.

EXPRESS specification:

*)
SUBTYPE_CONSTRAINT lisp_shape_element_subtypes FOR Shape_element;
  ONEOF (Non_feature_shape_element,
         Edge_segment_vertex);
END_SUBTYPE_CONSTRAINT;
(*

4.5 ARM function definition

This subclause specifies the ARM function for this module. The ARM function and definition is specified below.

4.5.1 list_get_zone_name

EXPRESS specification:

LOCAL
      s : SET OF STRING := [];
    END_LOCAL;
    REPEAT  i := 1 TO SIZEOF(input) BY 1;
      s := s + input[i]\Characterizable_object.name;
    END_REPEAT;
    RETURN(s);

Argument definitions:

input: the specified set of Connection_zone_in_layout_template.

4.6 ARM rule definition

This subclause specifies the ARM rule for this module. The ARM rule and definition is specified below.

4.6.1 unique_land_physical_template

EXPRESS specification:

LOCAL
      esi : BAG OF External_source_identification := [];
      iid : BAG OF String := [];
      itype : BAG OF String := [];
    END_LOCAL;
    REPEAT i := 1 to SIZEOF(Land_physical_template) by 1;
      esi  := esi + Land_physical_template[i].pre_defined_classification_code[1];
      iid := iid + Land_physical_template[i].pre_defined_classification_code[1]\External_source_identification.source_id;
      itype := itype + Land_physical_template[i].pre_defined_classification_code[1]\External_source_identification.source_type;
    END_REPEAT;

Argument definitions:

Land_physical_template : the set of all instances of Land_physical_template.

Formal propositions:

WR1: For all members of Land_physical_template associated with a member of External_source_identification in the role of pre_defined_classification_code, no more than one member of Land_physical_template in that population may be associated with the same source_id attribute of External_source_identification and each member of that population shall be associated with the same source_type attribute of External_source_identification.
