/**
 * This allows a definition parsers to be dynamically represented by one instance
 * selected from a set of parsers, depending on the context.  For example, a single
 * Mule model may be defined across several file - the first file used defines the
 * model and subsequent uses extend it (for this particular case, see
 * {@link InheritDefinitionParser}).
 *
 * <p>Note that the sub-parsers must be consistent.  That includes matching the
 * same schema, for example.
