Another try, but this time it involves a bit of hacking and exposing
some Tiles internals.
Associate a preparer to vertical.motor that accesses to the stack of

 ArrayStack<AttributeContext> contextStack =
            (ArrayStack<AttributeContext>) tilesContext

Where ATTRIBUTE_CONTEXT_STACK has this value:

Get the element under the top of the stack, that it is the attribute
context of the parent definition (probably, it might be 2 under the
top, not sure) and transfer the attribute that is under the current
AttributeContext (parameter in the preparer).
Finally, in your template page do:

>  <tiles:insertDefinition name="vertical.motor" preparer="my.Preparer"/>
>  <tiles:insertAttribute name="description"/>

You can also associate the preparer in the tiles.xml file if you like.

Does it sound better? :-D
