Tiles value variable

Hi,
My tiles work but this is heavy to write all the path, very repetitive, so I want to do that :

Code:

---

<tiles-definitions>
    <definition name="index" template="/WEB-INF/jsp/index.jsp">
        <put-attribute name="title" value="/WEB-INF/jsp/header.jsp" />
    </definition>
[...]
</tiles-definitions>

---

I want to do that :

Code:

---

path="/WEB-INF/jsp/"
<definition name="index" template=$path"index.jsp">
        <put-attribute name="title" value=$path"header.jsp" />
    </definition>

---

Solution ?
