> For serializing objects of types that are not supported by typed bytes serialization,
applications might want to use a custom serialization format. Right now, typecode 0 has to
be used for the bytes resulting from this custom serialization, which could lead to problems
when deserializing the objects because the application cannot know if a byte sequence following
typecode 0 is a customly serialized object or just a raw sequence of bytes. Therefore, a range
of typecodes that are treated as aliases for 0 should be added, such that different typecodes
can be used for application-specific purposes.
