Review Comment:
In section 2.12 of the Shell Command Language:
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html
The shell execution environment is described as:
> Variables with the export attribute, along with those explicitly exported
for the duration of the command, shall be passed to the utility environment
variables
which works together with the docs you linked for the `export` special
built-in command, that notes that the effect of `export XXX` is to mark the
variable `XXX` with the export attribute.
