Description:	These are collections of attributes of the ZIO device
		hierarchy. Each collection contains both: standard
		attributes (described later) and extended attributes
		defined by each driver (not described in this document).
		A standard attribute can appear *only* one time in the
		device hierarchy (e.g. The attribute X can be in a <cset>,
		but it cannot be, at the same time, in a <chan> or a <zdev>
		level). In this documentation we indicate each attribute
		at all level, but remember that it can be available only
		in one level. If an attribute appears only on a single
		level it means that it can leave only there.
		Attributes that live in an high level automatically apply
		the configuration on all lower levels.

		This collection refers to a single instance of a device.
		Each driver can decide to support or not the standard
		attributes; if it supports the standard attributes it works
		as described in this document.

		Note: The permission on the standard attributes depend on
		the driver implementation
