All,

I would also like to discuss the "insert-sheets" attribute.  In working on implementing this attribute it has become clear to me that it doesn't interact well with "imposition-template" and is something that could be implemented on the Client side using "overrides" and "force-front-side", much like "cover-front" and "cover-back".  So I would also like to DEPRECATE "insert-sheets".

We'll be discussing my PPX prototyping this afternoon during the IPP WG concall...

I am not convinced that we *do* need it since the Client can easily prepare document data that doesn't need imposition, but if we do need it we could add a "media-sheet-ranges (1setOf rangeOfInteger(1:MAX))" Job Template attribute...
