The XOXO Validator has been updated to support pages that are not well-formed XML. An XML error is displayed, but the XOXO valid message is still displayed if there is valid XOXO data on the page.

Users on the New Blogger may be pleased to discover there is a nice third-party tool for generating a profile section that is hCard-compatible!

Roger Costello has created a nice introductory S5 presentation (more on S5) for hCards.

hCards, among other things, are a building block of hAtom.

Please note that no template is ever 100% hAtom compatible on Blogger. There are those that come really close, but datetime-design-pattern dates cannot be generated on Blogger and thus the ‘updated’ field is always invalid.
