The Ant manual [1] recommends <arg value="..."/> rather than <arg
line="..."/>.  Doing so needs more elements, but it's safer to use.

Why are you using the <java> task rather than the <xslt> task?  IMO,
using the <xslt> task makes using XML catalogs with Ant much easier.

You could also make a macro for the transformation so you wouldn't need
to repeat everything just to change three filenames.

    I don't know why it's showing as "beta" since it was in earlier
    versions of Ant than the Ant 1.7 currently documented at this URL.
