     The ePAPR 1.1 standard says:

2.3.2 model

Property: model
Value type: <string>
Description:
	The model property value is a <string> that specifies the
  	manufacturer=92s model number of the device.

	The recommended format is: =93manufacturer,model=94, where manufacture=
r
	is a string describing the name of the manufacturer (such as a stock
	ticker symbol), and model specifies the model number.

Example:
	model =3D =93fsl,MPC8349EMITX=94;
