Clarifications

¹ This is a text description of the given <DRM Control Link> instance's purpose.

² This value specifies which <DRM Expression> component, if any, controls the cmy_data. cyan field value of the affected <DRM CMY Colour> instances. If the value is zero, the cmy_data. cyanfield of those instances is not controlled.

³ This value specifies which <DRM Expression> component, if any, controls the cmy_data. magenta field value of the affected <DRM CMY Colour> instances. If the value is zero, the cmy_data. magentafield of those instances is not controlled.

⁴ This value specifies which <DRM Expression> component, if any, controls the cmy_data. yellow field value of the affected <DRM CMY Colour> instances. If the value is zero, the cmy_data. yellowfield of those instances is not controlled.

Example(s)

Consider a transmittal, produced with CMY colours, the <DRM Model Library> of which contains a <DRM Model> representing a car with a <DRM Geometry Model>, the geometry of which consists of <DRM Polygon> instances with <DRM Inline Colour> components.
This car model is instanced in many places throughout the transmittal, and the data provider wishes to vary its appearance depending on the <DRM Geometry Model Instance>. Consequently, each <DRM CMY Colour> instance in the <DRM Model> has a <DRM CMY Colour Control Link> instance, supplying the value of the yellow field of the <DRM CMY Colour> with a <DRM Variable>.
