XML-binary Optimized Packaging (original) (raw)

A Relationship to other specifications

This appendix summarizes the XOP dependencies upon underlying specifications, the nature of appropriate payloads for XOP and the means of extending XOP.

A.1 Dependencies

The XOP convention builds upon a number of underlying specifications. They are:

• XML (e.g., [Extensible Markup Language (XML) 1.0 (Third Edition)], [Extensible Markup Language (XML) 1.1]) - The XOP Document is encoded using any W3C recommendation-level version of XML (see 3.1 Creating XOP Packages). Formats that use XOP MUST identify which versions of XML are permissible for encoding the XOP Infoset. XOP does not constrain the use of any mechanisms defined by XML, including those explicitly allowing extensions, nor does it constrain the use of underlying specifications.
• Namespaces in XML (e.g., [Namespaces in XML], [Namespaces in XML 1.1]) - The XOP Document uses any W3C recommendation-level version of Namespaces in XML compatible with the version(s) of XML used. Formats that use XOP MUST identify which versions of Namespaces in XML are permissible for encoding the XOP Infoset. XOP does not constrain the use of any mechanisms defined by Namespaces in XML, including those explicitly allowing extensions, nor does it constrain the use of underlying specifications.
• Uniform Resource Identifiers (see [RFC 2396]) - The XOP Document uses URIs to locate parts in the XOP Package (see2.2 href attribute information item. XOP does not constrain the use of any mechanisms defined by URIs, including those explicitly allowing extensions, nor does it constrain the use of underlying specifications.
• Packaging Mechanism - XOP requires the use of a packaging mechanism that satisfies the requirements in 4 XOP Packages. One such mechanism MUST be in use, but XOP does not require a specific mechanism. Formats using XOP MUST identify at least one such mechanism permissible for creating the XOP Package, and MUST specify how each allowed mechanism is to be used for building the XOP Package.
  The relationship of one such mechanism to XOP, The MIME Multipart/Related Content-type, is specified in 4.1 MIME Multipart/Related XOP Packages.

A.2 Payload

The payload of a XOP Package is an XML Infoset. XOP constrains the range of admissible characters in the payload to those contained in the "Char" production of a W3C recommendation-level version of XML. Additionally, the Original XML Infoset cannot contain an_element information item_ with a [local name] of ofInclude and a [namespace name] of "http://www.w3.org/2004/08/xop/include". Finally, portions of the payload which are nominated for optimization in XOP MUST be base64-encoded data in the canonical lexical form of XML Schema base64Binary datatype (see [XML Schema Part 2: Datatypes Second Edition] 3.2.16 base64Binary).

A.3 Extension

XOP Documents allow extensions to the xop:Include element when they do not change its semantics. Changes to the semantics MUST be identified by a new namespace URI (i.e., they MUST define a newInclude element information item in another namespace).

The extensibility of the specifications underlying XOP is not constrained by their use in XOP.
