A question about the color profiles:

+  <defs
+     id="defs2">
+    <color-profile
+       id="color-profile4"
+       name="Artifex-PS-CMYK-Profile"
+       xlink:href="file:///usr/share/color/icc/ghostscript/ps_cmyk.icc" />
+    <color-profile
+       id="color-profile6"
+       name="Artifex-PS-CMYK-Profile"
+       xlink:href="file:///usr/share/color/icc/ghostscript/ps_cmyk.icc" />
+    <color-profile
+       id="color-profile8"
+       name="Artifex-PS-CMYK-Profile"
+       xlink:href="file:///usr/share/color/icc/ghostscript/ps_cmyk.icc" />
+  </defs>

I don't think it makes sense to includes these file://usr/share/ URLs,
as they are rather useless on Guix System.  If these xlink:href
attributes were simply removed, would SVG-displaying applications still
automagically find the colour profiles? 

If not, then I guess we'll have to simply live with that
(and keep /usr/share for now).  Or maybe we could copy "ps_cmyk.icc"
to the "promotional" directory and use a relative link?
But then copying the SVG would break the link ...

Alternative solution: would converting to sRGB make the colours look bad?

Greetings,
Maxime
