Have you considered using a macrodef and elements?

Maybe something like:

<macrodef name="my-macro">
   <attribute name="id"/>
    <element name="includes"/>
   
    <sequential>
       <path id="@{id}">
          <includes/>
       </path>
    </sequential>
</macrodef>

Then you can supply whatever you want in <includes> as long as it 
adheres to <path> allowances....
