[2008] Which Baml Output items should be localized ?

Hello,
i created a project that is going to be localized.
I did run baml in order to generate a csv file that contains all the strings to be localized.
The question is :
Which strings should be localized ? The one that modifiable=="TRUE" , readable=="TRUE" and Category!="None"
and also the ones whose resource key ends with System.String.$Content (for string resources) ?
In general, which items should get localized and which not..
