type - The type of the value that is returned by this AttributeDefImpl instance.
accName - The name that should be used to acquire the AttributeDefImpl value from the owning StructureDefImpl. If The owning StructureDefImpl instance is dynamic then this should be a map key. If the owning StructureDefImpl instance references a a JavaBean then this should be a JavaBean property name.
