It looks like they do define all major basic RAID disk layouts. (except
raid10,f2 of cause) . RAID1+0 is a derived format, maybe that is out of
scope of the DDF standard.

"A secondary virtual disk is a VD configured using hybrid RAID levels like
RAID10 or RAID50. Its elements are BVDs."

So apparently their Disk Data Format specification doesn't include hybrid RAID
levels.  This makes sense, as the _on disk_ layout of RAID 10 is identical to
RAID 1.

I was puzzled here. I think you mean:

"the _on disk_ layout of RAID 10 is identical to RAID 1 and RAID 0"

If that is what you meant, I think we agree on most things here.
