XML.org is open for business. "The new online service on Oasis' Web portal site--XML.org--will serve as a library for XML vocabularies, "or schemas," developed by specific industries, such as insurance, health care, and any other industry grappling with data exchange and e-commerce. It will also include general XML specifications, such as the Trading Partner Agreement Markup Language, which provides a common format for companies to define and execute business contracts over the Web."
