Description: This is a collection of ZIO buffer attributes. It
contains both: standard attributes (described later) and
extended attributes defined by each driver (not described
in this document). This collection refers to a single
instance of a buffer implementation. Each buffer
implementation can decide to support or not the standard
attributes; if it supports the standard attributes it
works as described in this document.
Finally, remember that there is a buffer instance of the
same implementation for each channel within the same
channel-set of your devices
Note: The permission on the standard attributes depend on
the buffer implementation
