As I know, we do not have a strict list of subsystems at all.
Or it is hidden somewhere in SOP, which would not make any sense,
because new ones appear too often.

See 3 comments below.

1. No, it isn't. You still say "from array of index definitions",
but it is not array. Please, fix.

2. [out] should be specified after @param, not after parameter
name (your current version is @param size[out]). Source:

3. No, it is not. This hunk is still literally absolutely the same.
Please, do it.
