Pannonian, got it right - but, I don't believe it is a clean sheet or allows for open demands from Iran. It does, however, force Iran into a possition of compliance with the UN sanctions concerning nuclear development, or face economic sanctions from even their good buds in China and Russia (er, maybe).

I seriously doubt the Iran leadership will comply, believing their "oil card" as being the only trump they need to encourage some States (atleast China) to ignore what ever sanctions maybe applied.

Further, it is only a win for Iran if they cease their uranium enrichment program, and allow UN inspectors into "all" their nuclear facilities. Sound at all familiar? [reference UN sanctions imposed on Iraq - prior to US invasion]
