Constraints:

Signature: result_no_incoming() : Boolean;
Description: The result output pins have no incoming edges.
Expression: true

Signature: one_clause_with_executable_node() : Boolean;
Description: No ExecutableNode may appear in the test or body part of more than one clause of a conditional node.
Expression: true

Signature: no_input_pins() : Boolean;
Description: A conditional node has no input pins.
Expression: true

Signature: matching_output_pins() : Boolean;
Description: Each clause of a conditional node must have the same number of bodyOutput pins as the conditional node has result output pins, and each clause bodyOutput pin must be compatible with the corresponding result pin (by positional order) in type, multiplicity, ordering and uniqueness.
Expression: true

Signature: executable_nodes() : Boolean;
Description: The union of the ExecutabledNodes in the test and body parts of all clauses must be the same as the subset of nodes contained in the ConditionalNode (considered as a StructuredActivityNode) that are ExecutableNodes.
Expression: true

Signature: clause_no_predecessor() : Boolean;
Description: No two clauses within a ConditionalNode maybe predecessor clauses of each other, either directly or indirectly.
Expression: true

Operations:

No additional operations.
