Ah, I see.

I had included a sample of the new output from 'drvctl -p' (show propery 
dictionary) which includes the new information.  Here it is again:

# drvctl -p atabus0
Properties for device `atabus0':

"http://www.apple.com/DTDs/PropertyList-1.0.dtd";>

        <key>interface-attributes</key>

                        <string>ata_hl</string>
                        <key>locators</key>
                        <array>
                                <string>drive</string>
                        </array>
                </dict>
                <dict>
                        <key>attribute-name</key>
                        <string>atapi</string>
                </dict>
        </array>
</dict>
</plist>

There is a new optional array of (sub)dictionaries for the interface-
attributes.  It will not be present if there are no possible children.

In each interface-attribute's dictionary, there is an optional array of 
locators in addition to the interface's name.

With some minor modifications to drvctl(8) (which I'm also working on), 
you could request only the interface-attributes info using the command:

# drvctl -p atabus0 interface-attributes
Array:
