Exported task list does not contain task Activity data

[toddgee]

The XML document containing the exported task data does not contain Activity data. Deleting and re-importing tasks from an exported backup file will not restore Activity data.

Since this project is dead, this follow-up probably doesn't help anyone.
However, just in case....
I was stuck on Tasquid and wanted to move to Tasks. I've contributed code to Tasks to allow import/export of comments with backup XML. However, getting data out of Tasquid DB was a separate challenge.
I chronicled it all here:
tasks/tasks#373
If you need to get your data out of Tasquid and into Tasks, this should help. cheers!
