In concept, this is what Clay allows you to do. The "component" is the outer most definition. Under that you can create composition using the "element" which has to reference a top-level definition. So, in Antonio's example, the nested tile definition (path="/header2.jsp") would need to reference a top level definition and in doing so would extend it like a java anonymous class. Clay symbols are similar to the "put"s. The difference is that they are pushed to all nested definitions and not just a single level. They are scoped from the outer to the inner. They can be overridden at any level. This functions pretty much like Antonio describes below.
