Not quite,
A new selector would need to be typedefed in
   org/apache/tools/ant/types/defaults.properties
The problem is that the name "modified" (in this case) would
then be used up and could not be used for
example for a <modified> task, or (typedefed) condition/filter.

The solution to this namespace problem would
be to use roles.

I have (not synced up) code that adds a "role" attribute
to typedef which allows the context of the definition to
be limited to  add(Type x) and ant-type. This would have
the effect of allowing removing the hard-coding of the current selectors,
conditions, filters etc, placing the definitions in the antlib.xml for
ant.
However, I think it may be
better to wait for ant 1.7 to introduce another feature.

Peter.
