* Allow mappers to be genericised so that particular features can be modified 
  during mapping. Something similar to 
 
 <fileset ...>
   <include name="*.sh"/>
   <mapper type="unix-permissions">
     <param name="user" value="ant"/>
     <param name="group" value="ant"/>
     <param name="mod" value="755"/>
   </mapper>
 </fileset>

* Allow include/exclude tow work with multiple characteristerics of a file.
  ie include into fileset if file is readable, modified after 29th of Feb,
  has a name that matches patter "**/*.java" and the property "foo.present"
  is set. Something similar to 
 
 <include>
   <item-filter type="name" value="**/*.java"/>
   <item-filter type="permission" value="r"/>

   <!-- could optionally be directory/or some other system specific features -->
   <item-filter type="type" value="file"/> 
   <item-filter type="modify-time" 
                operation="greater-than" 
                value="29th Feb 2003"/>
 </include>

* provide datatypes through property tag and remove need for separate free
  standing entities. ie
  <property name="foo">
    <fileset dir="blah">
     <include name="*/**.java" />
    </fileset>
  </property>

* provide support for non-hardwired (ie loadable) low-level 
  components (mappers/itemset-filters/converters). Allow them to be 
  loaded in either global or a new classloader.

* provide support for non-hardwired (ie loadable) converters.

  /i.e. make the hardcoded rules from IntrospectionHelper pluggable/

* Make all datatypes interfaces to allow them to be customized in many
  ways.

* Set arithmetic for fileset/patternset/*set

* inheritance of ant properties/datatypes/context etc in project hierarchy

* inheritance of between ant datatypes. ie fileset A inherits from
  fileset B (includes all entries in A).

* Homogenize notion of PATHs and filesets.
