I checked the windows compatibility with help of SAMBA: "delete_child" 
and "delete" is really mapped to corresponding NTFS permissions. But 
this mapping was ignored when I tried to delete a file.
I have no idea, why these two permissions supported by FreeBSD. May be, 
it's a simply non-working clone from Solaris, where it's permissions 
really works.
