That is why an ISO standard is made so that anyone can implement it freely.
Implement freely? what? OOXML??
Are you nuts?
Please stop crapping and wasting other people's time if you have no idea about what in the world you're talking about!
Oh wait, you're a fanboy, I forgot
I understand that MS fanboys have the excellent ability to not understand anything that MS is doing.
Anyways, the point is, which I'm quite sure you have no idea about, there is something called OSP with OOXML. MS's so called
Open
Specification
Promise which states that:
"As long as Microsoft participates in the revision process to completion, Microsoft irrevocably commits to apply the OSP to that future version of IS29500 [the OOXML specification]."
(OSP) -- a pledge it won't sue developers using OOXML -- will apply to future versions of the document format.
As you can see, Not only is MS saying that if you make a revision without MS participating in it, they will sue you, but also if MS drops OOXML, they will sue you if you continue with it!!
Also, it applies only for future versions, which means, if you try to implement OOXML in it's current format without consenting M$, they'll sue you. So much so for being a standard! Darn!!
So, in short, apart from not being a standard in itself, it's not open, so stop this crap daydreaming misconception of your's and stop saying sh!t that OOXML is open!
