WDF storage (IDE) stack;

Hi, Currently there is no WDF IDE/AHCI stack. I'm just begining to
learn WDF. Can anyone tell me if WDF supports storage stack? From the
documents, all I could find is that storage class/filter drivers are
supported, but I have no clue what/how to re-place the port/miniport
etc? If I want to write my own WDF storage stack for IDE/AHCI, what
all do I need to do (like which system provided driver's to replace)
and will my WDF storage stack be able to co-exist with the system
provided storage stack (disk/ataport/atapi/msahci .sys)? Any help/
opinion will be highly appreciated.
