If you replace Xerces 2.x (included with ant 1.5.x) with Xerces 1.4.4
or Crimson (included with JDK 1.4) you can validate against XML
Schemas. Xerces 2.x has schema validation turned off by default and
ant can only turn it on in a future 1.6 version (using an <attribute
... />).
I was able to get Crimson running on JDK 1.4 simply by removing
$ANT_HOME/lib/xercesImpl.jar. Crimson is considerably slower than
Xerces 2.x though :(.
69.4s jdk 1.3.1 xerces 1.4.4
53.2s jdk 1.4.1 xerces 1.4.4
51.6s jdk 1.4.1 crimson
18.9s jdk 1.3.1 xerces 2.2.1
15.4s jdk 1.4.1 xerces 2.2.1
If I recall correctly these times were from validating a ~5k document
with a very large schema 5000 times.
