Other W3C XML Technologies

XML Namespaces

In XML, element names are defined by the developer. This often results in a conflict when trying to mix XML documents from different XML applications.

XML Namespaces provide a method to avoid element name conflicts.

XML Linking (XLink, XPointer, and XML Base)

XLink allows you to insert links into XML documents.

XPointer allows the links to address into specific parts of an XML document.

XML Base is a standard for defining a default reference to external XML resources (similar to <base> in HTML).

XInclude

XInclude is a mechanism for merging XML documents using elements, attributes, and URI references.
