 * @class XMLTriple
 * @sbmlbrief{core} Representation of a qualified XML name.
 *
 * @htmlinclude not-sbml-warning.html
 *
 * A "triple" in the libSBML XML layer encapsulates the notion of qualified
 * name, meaning an element name or an attribute name with an optional
 * namespace qualifier.  An XMLTriple instance carries up to three data items:
 * 
 * <ul>
 *
 * <li> The name of the attribute or element; that is, the attribute name
 * as it appears in an XML document or data stream;
 *
 * <li> The XML namespace prefix (if any) of the attribute.  For example,
 * in the following fragment of XML, the namespace prefix is the string
 * <code>mysim</code> and it appears on both the element
 * <code>someelement</code> and the attribute <code>attribA</code>.  When
 * both the element and the attribute are stored as XMLTriple objects,
 * their <i>prefix</i> is <code>mysim</code>.
 * @verbatim
<mysim:someelement mysim:attribA="value" />
@endverbatim
 *
 * <li> The XML namespace URI with which the prefix is associated.  In
 * XML, every namespace used must be declared and mapped to a URI.
 *
 * </ul>
 *
 * XMLTriple objects are the lowest-level data item in the XML layer
 * of libSBML.  Other objects such as XMLToken make use of XMLTriple
 * objects.
