XML, XHTML, CSS, HTML

[Luigi Donatello Asero]

I understand that HTML is used for structure and CSS for the layout. But
what are XML and XHTML for?
Is XHTML the next evolution step after HTML? What about XML, then? Do you
know any NG about XML and XHTML?
Thank you very much in advance for your answers.

I don't know anything about NG but you might try:
