It would perhaps better not to use KoDocument but to store the values in the 
KSpread document. It has been discussed a few times, people have told that it 
should be done but it seems that it has never been implemented (at least, the 
filters never used it.)

The problems of using KSpread directly are multiple;
- it makes extra code in the filter system just for KSpread
- you cannot use koconverter with KSpread export filters
- it makes global KOffice export filters nearly impossible, for example to be 
able to export a complete document (Word with KSpread object for example) to 
HTML (which we cannot do now.)

Have a nice day/evening/night!
