Does any MS document clarify the behavior when a parent allows DELETE CHILD on an object but the object has a DENY DELETE

Thanks. I guess I should have looked at MS-FSA.

This appears to be the sentence:

If (Open.RemainingDesiredAccess.MAXIMUM_ALLOWED ||
Open.RemainingDesiredAccess.DELETE), the object store MUST set
Open.GrantedAccess.DELETE if AccessCheck(SecurityContext,
Open.Link.ParentFile.SecurityDescriptor, FILE_DELETE_CHILD) returns
TRUE.
