[JSR308] JSR 308 documents and tools released

[Bill Pugh]

Figure 1 shows:

@DefaultAnnotation(@NonNull)

We haven't found anyway to do this with JSR-175 annotations; you  
can't define an annotation that takes an arbitrary annotation as a  
parameter.
You also can't define subtypes relationships in JSR-175.

Is the ability to do this an extension in JSR-308? I didn't see it  
spelled out.
