/**
 * Contains context information for generating XML Signatures. This interface
 * is primarily intended for type-safety.
 *
 * <p>Note that <code>XMLSignContext</code> instances can contain
 * information and state specific to the XML signature structure it is
 * used with. The results are unpredictable if an
 * <code>XMLSignContext</code> is used with different signature structures
 * (for example, you should not use the same <code>XMLSignContext</code>
 * instance to sign two different {@link XMLSignature} objects).
 * <p>
 * <b><a name="Supported Properties"></a>Supported Properties</b>
 * <p>The following properties can be set 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 digested
 *      {@link Reference} objects 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>.
