+/**
+ * An immutable valid policy tree node as defined by the PKIX certification 
+ * path validation algorithm.<br />
+ * <br />
+ * One of the outputs of the PKIX certification path validation 
+ * algorithm is a valid policy tree, which includes the policies that
+ * were determined to be valid, how this determination was reached,
+ * and any policy qualifiers encountered. This tree is of depth
+ * <i>n</i>, where <i>n</i> is the length of the certification
+ * path that has been validated.<br />
+ * <br />
+ * Most applications will not need to examine the valid policy tree.
+ * They can achieve their policy processing goals by setting the 
+ * policy-related parameters in <code>PKIXParameters</code>. However,
+ * the valid policy tree is available for more sophisticated applications,
+ * especially those that process policy qualifiers.<br />
+ * <br />
+ * {@link PKIXCertPathValidatorResult#getPolicyTree() 
+ * PKIXCertPathValidatorResult.getPolicyTree} returns the root node of the
+ * valid policy tree. The tree can be traversed using the 
+ * {@link #getChildren getChildren} and {@link #getParent getParent} methods. 
+ * Data about a particular node can be retrieved using other methods of 
+ * <code>PolicyNode</code>.<br />
+ * <br />
+ * <b>Concurrent Access</b><br />
+ * <br />
+ * All <code>PolicyNode</code> objects must be immutable and 
+ * thread-safe. Multiple threads may concurrently invoke the methods defined 
+ * in this class on a single <code>PolicyNode</code> object (or more than one) 
+ * with no ill effects. This stipulation applies to all public fields and 
+ * methods of this class and any added or overridden by subclasses.
