```
/**
* Defines if the type allows an empty set of bytes ({@code new
byte[0]}) as valid input. The {@link #validate(Object, ValueAccessor)}
* and {@link #compose(Object, ValueAccessor)} methods must allow empty
bytes when this returns true, and must reject empty bytes
* when this is false.
* <p/>
* As of this writing, the main user of this API is for testing to know
what types allow empty values and what types don't,
* so that the data that gets generated understands when {@link
ByteBufferUtil#EMPTY_BYTE_BUFFER} is allowed as valid data.
