### Question:
TagDefinition extends NamespaceOwnedElement implements HasMultiplicity { @Override public void accept(final Visitor visitor) { visitor.visit(this); } TagDefinition(final Identifier id, final List<TaggedValue> taggedValues, final String name,
            final Multiplicity multiplicity);  TagDefinition(final Identifier id, final String name, final Multiplicity multiplicity); @Override void accept(final Visitor visitor); @Override Multiplicity getMultiplicity(); @Override String toString();  }### Answer:
@Test public void testAccept() { tagDefinition.accept(visitor); }
