Thanks for pointing me there, Jens,
but I couldn't actually find any explanation on how validators and designing
tools are supposed to validate HTML5 and future HTML standards correctly.
How are such tools to behave if certain tags/attributes will get deprecated
in future HTML versions? What if new tags/attributes will be added?
I'm currently developing for a customer who has just rolled out IE8.
Developing here is a matter of try & error because Visual Studio 2010
validates completely apart from target platform.
I believe that applications advertising to implement a versio of a standard
should only do so if the fully do so. So validation will actually have any
benefit.
But validation against any definitive version of a standard seems impossible
to me if there's no version information given.
So I see a lack of definition here.
Cheers,
Axel
