8    /// The expression's input is an object named "device", which carries the following properties:
9    ///  - driver (string): the name of the driver which defines this device.
10    ///  - attributes (map\[string\]object): the device's attributes, grouped by prefix

21    ///
22    /// The device.driver field can be used to check for a specific driver, either as a high-level precondition (i.e. you only want to consider devices from this driver) or as part of a multi-clause expression that is meant to consider devices from different drivers.
23    ///
24    /// The value type of each attribute is defined by the device definition, and users who write these expressions must consult the documentation for their specific drivers. The value type of each capacity is Quantity.
25    ///
26    /// If an unknown prefix is used as a lookup in either device.attributes or device.capacity, an empty map will be returned. Any reference to an unknown field will cause an evaluation error and allocation to abort.

32    ///   cel.bind(dra, device.attributes\["dra.example.com"\], dra.someBool && dra.anotherBool)
