non-brittle granular includes

[Samuel Wales]

can body text or paragraphs be included upon export?

i have a file like this:

* top
** a
b [these are paragraphs]

c [another paragraph]

d [another paragraph]
** e
# i'd like to include b and c here redundantly
# because i want to export e separately

f [paragraph]
** g

i'd like to use #+NAME or <<name>> or org-id to specify the thing to
include, and to reference it.

however, the #+include syntax doesn't quite allow less-brittle references.

is there anything that can do this?  it isn't a huge issue, but i have
run across it a few times over many years.
