XML Technologies including XML, XML Namespaces, XML Schema, XSLT, Efficient XML Interchange (EXI), and other related standards.

            XML Essentials 
            
        XML is shouldered by a set of essential technologies such as the
        infoset and namespaces. They address issues when using XML in
        specific applications contexts.
      
            Efficient Interchange 
            
	  XML standards are omnipresent in enterprise computing, and are part of the foundation of the Web. Because the standards are highly interoperable and affordable, people have wanted to use them in a wide variety of applications. However, in some settings (on devices with low memory or low bandwidth, or where performance is critical) experience has shown that a more efficient form of XML is required.
	 
            Schema 
            
        Formal descriptions of vocabularies create flexibility in
        authoring environments and quality control chains. W3C’s XML Schema,
	SML, and data binding technologies provide the tools for quality
	control of XML data.
      
            Security 
            
        Manipulating data with XML requires sometimes integrity,
        authentication and privacy. XML signature, encryption, and
	xkms can help create a secure environment for XML.
      
            Transformation 
            
	  Very frequently one wants to transform XML content
	  into other formats (including other XML formats).
	  XSLT and XPath are very powerful tools for
	  creating different
        representations of XML content.
      
            Query 
            
        XQuery (supported by XPath)
	is a query language for XML to extract data, similar
        to the role of SQL for databases, or SPARQL for the Semantic
	Web.
      
            Components 
            
        The XML ecosystem is using additional tools to create a
        richer environment for using and manipulating XML
        documents. These components include style sheets, xlink
	xml:id, xinclude, xpointer, xforms, xml fragments, and
	events.
      
            Processing 
            
        A processing model defines what
        operations should be performed in what order
	on an XML document.
      
            Internationalization 
            
        W3C has worked with the community on the internationalization
	of XML, for instance for specifying the language of XML content.
      
            Publishing 
            
XML grew out of the technical publication community.
       Use XSL-FO to publish even large
       or complex multilingual XML
       documents to HTML, PDF or other
       formats; include SVG diagrams
       and MathML formulas in the output.
