Shouldn't it be <code>NgAnnotation</code>s or <code>NgAnnotation</code>-annotated objects or objects annotated with NgAnnotation or its subclasses... Hmm, maybe just "NgAnnotations" (no code font) is better. :)

I'm not a big fan of sprinkling code font everywhere, but if we're going to do it, we need to be precise about including only the characters that are in the class name.

There's also the issue of what to call classes that have been annotated, and differentiating them from the classes used in the annotation. (E.g. you wouldn't call a class with an @MirrorsUsed annotation a MirrorsUsed.) I don't know enough about this particular bit of writing to know which it's referring to—the actual class of the annotation, or the class it's annotating.
