Sorry, new in this thread.

But what do you mean with 'optional' attribute?
Scenario:
  <zip destfile=3D"dir1/myzip.zip">
      <fileset dir=3D"mybasedir" includes=3D"subdir1/,subdir2/"/>
  </zip>

- "dir1" must exist, usually you add a <mkdir dir=3D"dir1"/> before the =
<zip>
- "mybasedir" must exist (I think); here the optional attribute could =
make
sense
- "subdir1" and "subdir2" don=B4t have to exist; only if they exist =
they are=20
  selected by the DirectoryScanner used by <fileset>

So the only scenario for your "optional" suggestion would be
  <zip ...>
      <fileset dir=3D"may-not-exist" optional=3D"true"/>
      <fileset dir=3D"must-exist"/>
  </zip>
So that task wouldnt fail.
