Mutt,at one time the CAA used to increase the VMCG by 7knots for a crosswind additive,but with time(and poss JAA involvement have dropped this reference).
There are quite a few variations of the SAS chart,AIP Canada etc(althought the danger of the AIP is that it shows the max'crosswind component at 45knt on a 'dry' runway) the SAS chart depicts a more realistic 35knt(certification/demonstrated)..Contact a SAS airline/pilot for the chart.
