The fill style "NONE" is different from "SOLID + 100% transparency" and 
has to be retained.

(1) You see the difference, when you use style inheritance. If you set 
the color to "yellow" in the child, you will indeed get yellow in case 
the parent has FillStyle="NONE" and the child will be transparent in 
case the parent has "SOLID + 100% transparency".

(2) When you use area fill for paragraph background, then you get 
interoperability problems, because other applications (I have tested 
AOO4.2 and Word 2010) do not get the transparency for paragraph 
background correctly, but interpret FillStyle "NONE" correctly.

(3) If a search for attributes will be implemented, then 
FillStyle="None" is surely different from "SOLID + 100%transparency".

(4) You need "NONE" anyway, because "NONE" is value of enum FillStyle in 
the API.

Kind regards
Regina
