I heard you the first time :-p I just was not sure what the implications
would be to use it. Hence I suggested a vendor specific property.
However, looking up and reading the definition in ePAPRv1.1 I suppose it
is fine to use the model property:
Property: model
Value type: <string>
Description:
The model property value is a <string> that specifies the manufacturer’s
model number of the device.
The recommended format is: “manufacturer,model”, where manufacturer is a
string describing the name of the manufacturer (such as a stock ticker
symbol), and model specifies the model number.
