This document provides specifications for BizTalk Framework 2.0. New features in this major revision include transport bindings (HTTP only; SMTP, and FTP to be added), reliable message delivery, MIME encoding for attachments and security based on S/MIME and PKCS (to be added).

This release has also been influenced by recent standards efforts, including XML Schema Part 1: Structures, XML Schema Part 2: Data types, XML-Signature Syntax and Processing, and most notably the Framework has been redefined to be Simple Object Access Protocol (SOAP) 1.1 compliant.
