In the OOo plugin the style information is available
*before* writing the output. In the Excel plugin the cell
content determins the style (i.e. color) of it. I would have
to do a pre-processing step to create all the classes
(styles) and put them into the header
(anybody to suggest how?).

But this is not where the discussion is heading ... the
style information should be neither in-line nor in-header.

If it was to write a separate file (like a template), this
could be done I think (again: how?).

Right, putting each color into a class/ft could explode
the style section.

We now have about 25 basic colors but I don't know what
others will come up with (or other projects).

For me it would be sufficient to have @class. No new
attribute @ft needed. The question is, how and where
can I define the classes? They need to make it into
CSS-classes at the skinning stage (like Excel-CSS).

I still cannot see a big difference between a
       class=" background_color__ff0000  "
and a style="{background-color=#ff0000;}"

Both look to me like style information ;-)

This is different in the OOo where styles are used
consistently throughout the document.
In the Excel plugin it's basically a one-time use.


Just another bit ;-)
