The proper construction is of course to use an adjective, which is easily done without changing the sense and meaning of the sentence, to wit:
''Please note, the below-mentioned indicators are not an all inclusive list.''
Granted, ''below-mentioned'' is rarely seen, and for a good reason. The fact is that the author is also stylistically damaged, too. Ordinarily, one would list the indicators, and then write something like:
''Please note, the above-mentioned indicators are not an all-inclusive list.''
As I noted, I’ve been seeing it more and more lately: “the below listed”, “the below cited”, “the below mentioned”, rather than the acceptable “the facts listed below”, or equivalent.
