  Added:       proposal/embed/src/java/org/apache/tools/ant/taskdefs
                        XMLDOM.java
  Removed:     proposal/embed/src/java/org/apache/tools/ant/types
                        XMLDOM.java
  Log:
  Moved XMLDOM to taskdefs. There is no difference between type and
  task any more, and it may do some active stuff in execute()
