specific microformats validators

validator project
There has been a suggestion to host an "official" microformats validator at microformats.org.
Ideas:
- hCard validator is open-source (BSD-licensed) and extensible enough to support other microformats (it's mostly a matter of hooking up XSLT templates that extract microformat data and find errors). The codebase is pretty clean, UI is internationalized.

Who wants to help make this happen, and what do you need?

Optimus validator is not working for the moment

Please add issues to the optimus-issues page.
