Thanks that works.
<project xmlns:myns="antlib:com.acme.ant.antlib">
<taskdef uri="antlib:com.acme.ant.antlib"
resource="com/acme/ant/antlib/antlib.xml"
classpath="path/to/antlib.jar"/>
So I have the following mappings:
* xml namespace (on project tag) maps to the antlib-URI
* the antlib-URI (uri on taskdef) maps to the resource (on taskdef) on the
given classpath (on taskdef).
