Description:


This class represents the ID attribute type. This is also a tokenized type of attribute and values of ID type attributes must match legal names as defined in the XML 1.0 specification. 

For an XML document to be valid, ID values must uniquely identify the elements which bear them; i.e. A name must not appear more than once in an XML document as a value of this type. Also for validity purposes, an ID attribute must have a declared default of #IMPLIED or #REQUIRED in the DTD.

ID and IDREF attributes together provide a simple inside-the-document linking mechanism with every IDREF attribute required to point to an ID attribute.
