When it comes to XML, one can use this W3C specification for internet media but in the event that you are doing so you will also need to make use of the XPointer system as a means of addressing these media components. The most recent release of XPointer can then be subdivided in 4 unique but necessary specifications which include the framework necessary to identify those media fragments, there is a positional element in the use of XPointer, namespace specifications as well as an XPATH addressing scheme. In its most simplified format, the XPointer is needed as a means of addressing the structure of the XML. This structure includes textual content as well as the objects that are created during the parsing of the XML file.
XPointer allows for the XML specification to be more user friendly and can be seen in some actions such as drag and drop used on an AJAX based website development. It was Sun Microsystems that developed the XPointer technology for its integration into XML and much like the vast majority of those Sun Microsystems developments, it is held under a royalty free usage licensing so that all web developers would be able to make use of the development.
