This sound just like what I was thinking about... The best thing to do I 
guess is to have the <meta> element totally transparent to VCDXBuild so 
that We gui-guys can use them as we wish...

Okay... What I'm trying to do is to make VCDComposer more helping when 
changing formats (it have some checks today, but not in all details)...

Okay, that's what I thought too... Good to have it confirmed to...

That was my guess also...

I'm implementing extended output dialog from the create image process, to 
use the gui- and progress flags.
BTW what I do today is that I extract the version number from the text 
returned on -V option (to see if I can use the gui- and progress flags)... 
One thing that popped into my head was that it would be nice (for this 
purpose) to have an option that returns the version number only... Would 
make it easier to get the information... (I rely on the format of the text 
returned today but it feels a bit "hacky" :-)
