If you are using a version of Ant later than the 3.1 release, that is
correct -- Ant has been made JAXP-compliant so that you can use any
JAXP-compliant parser.  If you use the reference implementation, you'll
need "jaxp.jar" and "parser.jar" on your class path -- for any other
parser, replace these as described in your parser's documentation.

I assume you are using the "ant" script that came with the release,

On Unix systems, you can set an environment variable called JAVACMD to
include command line options to change the memory allocation.  For
example you might want to do this:

    export JAVACMD="java -mx64m"

to set the maximum heap to 64 megabytes.  On Windows systems, you can
modify the "ant.bat" file to include this switch for you.
