Web enabled content interchange, manipulation and presentation for
enterprises
implementing XML-based initiatives.

"We're very pleased to partner with Extensibility to help ensure XMetaL's
continued
leadership as the standard for XML content authoring," said Jonathan Sachs,

infrastructures for
companies and their trading partners.  The product offers a designing

solutions to implement XML-based e-business initiatives.  With support and
