The World Wide Web Consortium (W3C) has recommended two related specifications designed to link pages written in Extensible Markup Language (XML). The first, XML Linking Language, or XLink, became a candidate recommendation nearly a year ago and achieves its final recommendation status more than six months past its scheduled approval. The recommendation provides a means of linking to and from discrete parts of a single XML document that is more flexible than HTML linking methods.
The second recommendation, XML Base, lets XML document authors specify a certain page or domain to which subsequent links will lead. Once that base address is specified, authors can shorten addresses to indicate only discrete parts of that page.
