You will want Ant's trunk and a PropertyExpander like
http://svn.apache.org/viewvc/ant/sandbox/antlibs/props/trunk/src/main/org/apache/ant/props/NestedPropertyExpander.java
8-)
You can't have nested properties with Ant 1.7.1, but since you are
modifying Ant's source code anyway, you might as well switch to Ant's
trunk now - a release shouldn't be too far into the future.

No, there is not. Ant parses ${} constructs by searching up to the next
closing brace, ignoring any newly opened ones by default.
${${n}${m}} is turned into
"value of property ${n" + "value of property m" + "literal }"
and since there is no property named "${n" it is expanded to ${${n}
