I think ISO implies the invariant culture.  So should be conditional on 
invariant culture.

Yes.

Issue 21, says No. And I agree with your comment that this may not be *right*.

I think the fact that the ISO patterns only use the invariant culture should be 
seen as incidental - it certainly doesn't mean that whenever you use the 
invariant culture, you're trying to use the ISO format.

If we want to be selective about this, the simplest way is to use a new 
character. ";" seems like an obvious choice, having both a comma and a dot in 
it. I suspect it rarely crops up as literal text which would need escaping, 
too. (I'm still somewhat of a mind to forbid any unquoted literal text other 
than space, but that's a separate matter.)

So the extended ISO format would just become:

    yyyy'-'MM'-'dd'T'HH':'mm':'ss;FFFFFFF

Thoughts?

So simple using ";" You got my vote.

Implemented (not committed); still need to update docs. Will be in 1.0.
