Using KMDF for volume upper filter

I need to write a volume upper filter driver for volume class. So my question is – is it possible to use KMDF to write such filterdriver and if so which sample in DDK best suitable for that. Or WDM is the only way to do write upper filter driver.

I looked at thread “http://www.osronline.com/showThread.cfm?link=180620” but was not able to understand couple of comments.
Does WDK have new sample since then for KMDF. Are there any WDM driver sample I can look at and convert it to KMDF.

KMDF is fine for filtering any pnp stack including volumes.
Unfortunately there are not a lot of filter examples -
\WinDDK\7600.16385.1\src\general\toaster\kmdf\filter\generic is the
basic KMDF filter.
