Extensible linking Language (XLL)

XLL formally was called XLink. XLL stands for Extensible Linking language and consists of the following parts:

  • XPointer - It is built on XPath and it establishes a common system to specify node locations. It allows for locating data that is not a complete node.
  • XLink - Advanced linking. It links to multiple destinations, is bi-directional and allows for links to be displayed on other documents
  • XInclude - Merges XML infosets into one infoset.
