Use of an annotation without @Target meta-annotation on a module declaration

I wanted to alert readers of this list to the fact that JEP 359 (Records) will add a new declaration context for annotations, and hence there will be a new enum constant, RECORD_COMPONENT, of java.lang.annotation.ElementType.
With regards to the recent discussion on this list, I have followed the agreed suggestion:

In other words, a program with no @Target meta-annotation will be applicable in the new RECORD_COMPONENT context.
