Yes. we would like this driver to be merged in the next cycle(6.5).
Based on the community feedback on v1 version of the driver, we removed 
all references to OASIS standard and at this time this is an intel 
vendor driver.

The v1->v2 change log reflects this update.
v1 --> v2: link [1]
  * removed the OASIS reference in the commit message to make it clear
    that this is an Intel vendor specific driver

Any IDPF specification updates would be handled as part of the changes 
that would be required to make this a common standards driver.
