/**
 * Contains context information for validating XML Signatures. This interface
 * is primarily intended for type-safety.
 *
 * <p>Note that <code>XMLValidateContext</code> instances can contain 
 * information and state specific to the XML signature structure it is 
 * used with. The results are unpredictable if an 
 * <code>XMLValidateContext</code> is used with different signature structures 
 * (for example, you should not use the same <code>XMLValidateContext</code> 
 * instance to validate two different {@link XMLSignature} objects).
 * <p>
 * <b><a name="Supported Properties"></a>Supported Properties</b>
 * <p>The following properties can be set by an application using the 
 * {@link #setProperty setProperty} method.
 * <ul>
 *   <li><code>javax.xml.crypto.dsig.cacheReference</code>: value must be a
 *	{@link Boolean}. This property controls whether or not the
 *	{@link Reference#validate Reference.validate} method will cache the 
 *	dereferenced content and pre-digested input for subsequent retrieval via
 *      the {@link Reference#getDereferencedData Reference.getDereferencedData}
 *	and {@link Reference#getDigestInputStream 
 *	Reference.getDigestInputStream} methods. The default value if not 
 *	specified is <code>Boolean.FALSE</code>.
