It's been mentioned on several different fora over the years.  I suspect
that I first read about it on the fontforge lists.

These look like a reasonable discussion:

http://typedrawers.com/discussion/192/making-ot-ttf-layout-features-work-in-ms-word-2010

http://typophile.com/node/90383

The first page above says that DSIG is only a flag for glyf fonts; cff
always get the otf treatment.

You'll note a familiar name in the replies on the latter page.
