I now added "RIF-BLD" in front of "document formula" in the definition.

I now added a definition of "RIF-BLD document" as a "RIF-BLD document formula"
with or without an annotation. This is in the short section about annotations.

I added a clarifying clause that annotations are allowed for subformulas and
subterms. However, I did not add annotated formulas among the bullets in the
main definition, since it would complicate things. This is because, I assume,
we do not want annotations to be added to already annotated terms and formulas.
So, the nice recursive nature of the definitions would have to be spoiled with
qualifications.
