for the
attributes it implements. The given clazz
must have a public no-arg constructor.
For all other attributes it calls the given delegate factory as fallback.
This method can be used to prefer a specific AttributeImpl
which combines
multiple attributes over separate classes.
Please save instances created by this method in a static final field, because
on each call, this does reflection for creating a MethodHandle
.
