Currently I am storing the calendar data as an Xml string by using the Schedule.SaveToXml method.

However I noticed that the Xml string is growing radiply.
When investigating this I noticed 2 things:
1. Identical resources appear several times in the XML even with the same ID, version, etc...  Is this normal ?
2. For each <item> there are some sections <style>, <selectedstyle>, <pointedstyle> & <pointedselectedstyle> present in the XML. They contain a lot of (static ?) info: colors, widths, etc... Do they need to be in the XML string ? I also have older versions of the XML and it seems that these sections were not present there. What could be the difference ?

Thanks,
