  Modified:    jelly/src/java/org/apache/commons/jelly JellyException.java
               jelly/src/java/org/apache/commons/jelly/impl TagScript.java
               jelly/src/java/org/apache/commons/jelly/tags/xmlunit

               jelly/src/java/org/apache/commons/jelly/tags/validate
                        AssertValidTag.java
  Added:       jelly/src/java/org/apache/commons/jelly LocationAware.java
               jelly/src/java/org/apache/commons/jelly/tags/junit
                        JellyAssertionFailedError.java
  Log:
  Added support for LocationAware tags and exceptions. This allows tags or exceptions to be
aware of where in a Jelly script they are invoked or thrown.
  
  This is particularly useful in JellyUnit. Now all the JellyUnit assertion failures throw
JellyAssertionFailedErrrors which include details of where in the Jelly script the failure
occurred.
