As it should :) They're all pretty much completely indistinguishable from

Probably. I'll have to dig some up. It should be noted that this is avoided
"like the plague" in the Gnome community and (iirc) its author doesn't fully
believe in its usefulness. It stands to wreck havoc with our XML parsers
too, but i guess that any Embedded/Structured FS will have that effect.

OLE2 is actually an "open" spec which MSFT just happened to create. There
are many freeware implementations of it (loala, libole2, others. See

I say in high confidence and in good faith that I believe that MSFT will
never change this spec, ever. One reason being that they would lose
inter-operability with all of their several billion/trillion documents in
existence. Their own company and several others depend on this SPEC's
existence (MSFT Office is an $11B a year business).
