Title: Optional components and separators

Hi, this looks awesome, however I can't get it to do what I want which is to match:
2007/12/31/ ||| 2007/12/31 ||| 2007/12/ ||| 2007/12 ||| 2007/ ||| 2007
My reason is that I am looking to use it for 'clean urls' - so the separators are mandatory between components, but optional afterwards.
I'm hoping you can help me out since you seem to have a great grasp of regex. If you'd prefer to email me then please use flotsam[at]scrwd[dot]com
Thanks.

What would this expression look like if I wanted to include years earlier than 2000?
