A representation of the XML 
KeyName element as
 defined in the 
 W3C Recommendation for XML-Signature Syntax and Processing.
 A 
KeyName object contains a string value which may be used
 by the signer to communicate a key identifier to the recipient. The
 XML Schema Definition is defined as:
 
 <element name="KeyName" type="string"/>
 
 A 
KeyName instance may be created by invoking the
 
newKeyName method of the
 
KeyInfoFactory class, and passing it a 
String
 representing the name of the key; for example:
 
 KeyInfoFactory factory = KeyInfoFactory.getInstance("DOM");
 KeyName keyName = factory.newKeyName("Alice");
