Where it says:

Q. Given that Google now looks at hidden content as potential spam, will 
invisible microformats be considered spam?

A. It is advisable not to hide information in your site, regardless of 
whether it is microformated or not. Microformats provide a mechanism for 
marking up visible content. Any mechanism for embedding invisible or hidden 
content risks being considered spam due to the fact that invisible 
(meta)data inevitably ends up being abused. Avoid invisible (meta)data. 
Publish visible data.
