Sysprep locations for multiple service packs

I've seen this KB article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1005593

It says "Microsoft has a different version of Sysprep for each release and service pack of Windows" and that we need to put the sysprep files in directories named 2k, xp, svr2003, etc.

What if we plan on making templates for multiple service packs of each OS? For example, XP SP1, XP SP2, XP SP3, etc?

Or will the sysprep files from XP SP3 work on all previous service packs?

Additionally, what about the difference between 2003 R1 and 2003 R2?

Thank you.
