Rich SNippets Support for Custom Taxonomies

Is there any Plugin by default has the functionality to support Rich Snippets for Custom Taxonomies

I'm using WordPress Coupon Theme Clipper on My site Coupons where There is a CUstom Taxonmy Store, I want to add rich snippets for that

To the WPMU team, I'm not sure if I can post this here, If it violates please let me know & I will remove .

I have just joined today
