I think you'd have to de-reference the path and create a property with it.
A technique to return properties is to create a property file in your nested build.xml
and then on return to the calling root build.xml load (source) the property file.
So your nested/build.xml will contain the following:
<property name="myReturnValue" refid="yourRefID"/>
<propertyfile file="return_values.xml"
<entry key="returnKey" value="${myReturnValue}"/>
</propertyfile>
and in your calling build.xml:
<ant file="nested/build.xml"
inheritall="true"
inheritrefs="true"/>
<property file="nested/return_values.xml" prefix="new"/>
<echo message"value of returnKey = ${new.returnKey}"/>
NOTE:inheritall="true" and inheritrefs="true" are optional.
and prefix stops the new property values clashing with existing one.
I haven't tried it - should work, but might need a couple of tweaks.
