Just like any other result parameter, it can be set using OGNL 
(unfortunately delineated by "${}" instead of "%{}").

So try:
<param name="contentDisposition">${contentDisposition}</param>
and add a "public String getContentDisposition()" method to SMIGExport.

I really suggest adding a "contentLength" parameter, otherwise the 
framework may well have you generate the full content twice:  Once to 
determine the length, and again to send it.

And keep in mind, the value for "contentDisposition" should not be a 
fileName, but rather a disposition (I.E. "inline" or "attachment"), 
which can subsequently take a filename argument.

Here's an example putting that all together:

<param 
name="contentDisposition">inline;filename="${media.code}.Media.${size}.${media.suffix}"</param>
