This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document. For related introductory information, see: Processing.
W3C Recommendations have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the W3C Recommendation Track.
Group Notes are not standards and do not have the same level of W3C endorsement.
This specification describes the syntax and semantics of XProc: An XML Pipeline Language, a language for describing operations to be performed on XML documents.
An XML Pipeline specifies a sequence of operations to be performed on zero or more XML documents. Pipelines generally accept zero or more XML documents as input and produce zero or more XML documents as output. Pipelines are made up of simple steps which perform atomic operations on XML documents and constructs similar to conditionals, iteration, and exception handlers which control which steps are executed.
This document defines two new, optional templates designed to make it easier to construct documents within an XProc pipeline using values computed by that pipeline.
This document contains requirements for the development of XML Processing Model and Language, which are intended to describe and specify the processing relationships between XML resources.
Below are draft documents: Last Call Drafts, other Working Drafts. Some of these may become Web Standards through the W3C Recommendation Track process. Others may be published as Group Notes or become obsolete specifications.
This specification defines several XML processor profiles, each of which fully determines a data model for any given XML document.
