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.
Completed Work
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.

XML has been designed for ease of implementation and for interoperability with both SGML and HTML.

For historic reasons, some formats have allowed variants of IRIs that are somewhat less restricted in syntax, for example XML system identifiers and W3C XML Schema anyURIs. This document provides a definition and a name (Legacy Extended IRI or LEIRI) for these variants for easy reference.

The Efficient XML Interchange (EXI) format is a compact representation that simultaneously optimizes performance and the utilization of computational resources. The EXI format was designed to support XML representation. With a relatively small set of transformations it may also be used for JSON, a popular format for exchange of structured data on the Web.
