icc-color: I am looking for a working sample...

Hi

I try to define an icc-color in my SVG, bu tit doesn't work.

First, I try to define a color-space (a local icc file) as "myCMYK".

-- SNIP START --

  <defs>
    <style type="text/css">
      <![CDATA[
        @color-profile { src:="cmykprof"; name:"myCMYK"; 
rendering-intent:"saturation";}
      ]]>
    </style>
  </defs>

-- SNIP END --

Then I define the icc-color like "fill:rgb(26,23,27) 
icc-color(myCMYK,0,1,0.8,0.1);" for example.

But it doesn't seem to work.

What could be wrong?
Has anybody a working example (svg file)?

Thanks
Hans
