I don't see that as doable; that implies that the structure of the
page itself is variable. A component's id, just like its type and
parameter bindings, is part of the static structure that is essential
to Tapestry's ability to share a single page instance across multiple
threads, or share requests across multiple servers in a cluster.
Typically, you will use an Environmental object to coordinate an outer
component (that pushes an object into the Environment) with an inner
component (that pulls the environmental out of the Environment).
