I can't really understand why XML is used to create new languages, IF my knowledge don't fail XML does nothing at it own, and how can you create new languages such as WML

XML is an extensible (hence the X) markup specification. It permits extensions, provided that they conform to the XML spec. That means you can create a set of tags and rules for a specific purpose: like XHTML.

So you are saying that w3c wrote HTML again but following the strict rules of XML, and creates the new XHTML write?
XML simply just a set of rule

You can think of XML as a set of rules for creating sets of rules. Its a meta-standard.

Isn't this a picture of Bill Gates?

Do you realize you could easily be labeled as a "troll" with this kind of "avatar" in a Gentoo forum?

XML is a set of rules for use in creating documents which can be easily read by an XML parser...

XML is a set of rules for use in creating new document formats.

A DTD is a set of rules. XML should be used in conjunction with DTD so that your XML documents conform to your own rules... That is, if you specified that a <para> can only appear inside a <section> but you forgot to do so, the XML parser will not notice anything wrong, but a XML parser with a DTD specification will.

By the way, HTML means nothing too. It is fortunate that people have decided to render it in one uniform way, rather than argue over whether <p> should cause one blank line before and after or not...

I see you haven't been fully integrated into hacker society yet, despite the post count.
