+
+    output intent       : only one profile per color space (and device class)
+    default color space : (theoretically) several profiles per color space possible
+
+    The default color space profiles define the current gamuts (part of/all the
+    colors we have in the document), while the output intent profile declares the
+    gamut of the output devices (the colors that we get normally a printer or
+    monitor).
+
+    Example:
+
+    I have two RGB pictures (both 'painted' in /DeviceRGB) and I declare sRGB as
+    default color space for one picture and AdobeRGB for the other. As output
+    intent I use ISO_coated_v2_eci.icc.
+
+    If I had more than one output intent profile for the combination CMYK/printer I
+    can't decide which one to use. But it is no problem to use several default color
+    space profiles for the same color space as it's just a different color
+    transformation. The relation between picture and profile is clear.

+\StartItem once it was ready, we could look into such a font  \FlushStep \StopItem
+\StartItem it tooks while to figure out the format due to rather fuzzy specs  \FlushStep \StopItem
+\StartItem it took us even more time to find out that the loader was flawed  \FlushStep \StopItem
+\StartItem one reason was that fonts themselves may have bugs or be incomplete \FlushStep \StopItem
+\StartItem then we changed to \FONTFORGE\ version 2 \FlushStep \StopItem
+\StartItem this made the missing pieces surface in more complex feature handling \FlushStep \StopItem
+\StartItem while implementing features the new table format was cleaned up \FlushStep \StopItem
