Hello Mr. Breton,
If you were to look near the end of the ColorChecker.cxf file provided by
X-Rite, you would find the MeasurementSpec block of XML (highlighted in blue
below). Inside this block is the DeviceIllumination (highlighted in red below),
which is what you are looking for.
<ColorSpecificationCollection>
<ColorSpecification Id="CSD50-2">
<TristimulusSpec>
<Illuminant>D50</Illuminant>
<Observer>2_Degree</Observer>
<Method>E308_Table5</Method>
</TristimulusSpec>
<MeasurementSpec>

<IlluminationAngle>45.0</IlluminationAngle>
<MeasurementAngle>0.0</MeasurementAngle>
</SingleAngle>
