Re: Custom Slide Shows: presentation:page-ids is unnecessary

Dear Dennis and TC members,

thanks for the detailed explanation. It had quite some interesting things in 
it I did not know.

I'm all for dropping the proposal when the above will be incoperated into ODF 
1.2. As Dennis has pointed out we already have what we need and it is easier 
for backward compatibility.
