1 Introduction

XML-binary Optimized Packaging (XOP), as specified in [XML-XOP], defines a method for the efficient serialization of XML Information Sets (XML Infosets) that have certain types of content. The XML-binary Optimized Packaging (XOP) Profile extends XOP to allow for the creation of more efficient implementations that process XML Infosets. This document, [MS-XOPP], describes the serialization rules for XML Infosets as MIME Multipart/Related XOP packages but does not specify how these XML Infosets are transmitted between network nodes.

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
