Thanks, I see.
I was thinking about a different scenario which, I realized, doesn't need
to be thought at all (heritance handling of an exiting file which has only
security attribute and its permissions are being modified in the condition
when the heritance was not considered during the security attribute
creation).

Fine, thanks.

No problem. Less than 0.1% of the files have security attribute
in general and this number is lessening in time.
