DeviceN colour spaces shall be defined in a similar way to Separation colour
spaces-in fact, a Separationcolour space can be defined as a DeviceN colour
space with only one component.
A DeviceN colour space shall be specified as follows:
[/DeviceN names alternateSpace tintTransform]
or
[/DeviceN names alternateSpace tintTransform attributes]
It is a four- or five-element array whose first element shall be the colour
space family name DeviceN. The remaining elements shall be parameters that a
DeviceN colour space requires.
