> Look at the functionality of c:import for context to this request:  http://docs.oracle.com/cd/E17802_01/products/products/jsp/jstl/1.1/docs/tlddocs/index.html
> That tag supports 2 attributes:  var and varReader.  These two variable prevent the included resource from automatically being including the output of current requests 'out' Stream.  They do the following:
> var - stores the output of the included resource as a String in the scoped variable identified by 'var'.
> varReader - stores a Reader to the included content in the scoped variable 'varReader'.
> Both of these would likely need the 'scope' attribute as well.
> The current use case I have for this is that I do not want to extend or modify the functionality of the included resource to serve my new requirement.  The change I need to make to the markup is fairly small, and would not want to have to maintain a new component for such a small change.  I want to include a transformed version of the included resource.  The addition of these two attributes would allow me to store the resultant markup and transform it before including it within my current request.
> I can certainly write this functionality myself (and will be using sling:include) but it would be nice if sling:include itself supported this functionality.
