    16   * <code>DefaultPattern</code> a default implementation of Pattern which can
    17   * take any XPath implementation or NodeFilter for defining the pattern.
    18   * <b>WARNING </b> this implementation causes a worst case, brute force XSLT
    19   * rule evaluation to be performed. Wherever possible the methods {@link
    20   * #getPriority}, {@link #getMatchType}and {@link #getMatchesNodeName}should
    21   * be overloaded to allow more rule filtering to occur.
