XX→YY: (Where XX is a valid source and YY is a valid destination address) If one of these bits is set to 1, it indicates that the medium changer device supports all Move Medium commands for which the source is element type XX and the destination is element type YY on the condition that the element addresses are valid. XX↔YY: A one in these fields indicates that the medium can be exchanged by means of the Exchange Media command between elements of types XX and YY on the condition that the element addresses are valid. XX→RA: These fields indicate the resources required to support the READ ATTRIBUTE commands for each element type XX. The media changer does not support the READ ATTRIBUTE command therefore these fields are set to 0. XX→WA: These fields indicate the resources required to support the WRITE ATTRIBUTE commands for each element type XX. The media changer does not support the WRITE ATTRIBUTE command therefore these fields are set to 0.
