In Drupal 6 for some content types when editing a node its replicated and keeps revisions for that content type by keeping vid (version id) for that in the table, But for some other content types it wont make new table entries when editing that content types . How is it like that ? Or is there any criteria to keep revisions for some content type only ?

When creating a new content type i can see the options as follows :
But as you can see , revision settings is inside submission form settings but **its disabled** here , how i can set revisions for particular content type only for some content type only .
