I'm not clear what you mean by either of these statements.

What I want to achieve is for all my pages to have a base layout, and some
of the pages have a slightly more complex layout, which itself is based on
the base layout.

Thanks
Ian

  In your example, you insert definition /top, which by extensions use
'base.jsp' as layout. In this later, you do <insert attribute="body" />.
Body
value is page /middle.jsp, wich is inserted. But, /midle.jsp is a page, not
a
definition. In /midle.jsp, you do <insert attribute="anotherBody" />, but
anotherBody is not defined for the page.

  You should either do  :

   * Pass the attribute value when you insert the page
   * Insert a definition using the page as layout, and declaring the
attribute
