A few minor errors there

Quote:

1/ You must have a doctype indicator and conform to its rule. For an example:
<!DOCTYPE html Public "-//W3C//DTD XHTML 1.0 Translation//EN"

Transitional not Translation

Quote:

4/You have to quote all your attribues, even simple ones such as

Ok apart from the point that align="left" would be invalid code as the align attribute is deprecated.

Quote:

5/ You must next your tags properly

nest the tags.

HTML is an application of the very flexible SGML.
XHTML is an application of XML which is extended from SGML.

XHTML so is much more strict then HTML. In HTML parts of the layout can be defined (, align=””, , , , …), in XHTML many of these 'only style'-elements or attributes don’t exist anymore. In general you can say in XHTML it’s more about content (style can be done with CSS). In HTML it’s still more a mix of style and content. Because of the more strict syntax XHTML should be more logical, synoptic, more easy to parse and thus faster.

Many people say XHTML is the future, but not everybody agrees with that.

little disadvantage: Internet Explorer still doesn’t support XHTML (however it can be dissolved with different-headers for IE).

Dissolved? you mean send the browser into melt down?

Though that is something of an exaggeration. XHTML1.1 when served as MIME type application/xhtml+xml is not supported in IE6 (and possibly IE7) but is Ok when served with the MIME type of text/html.

Nice semantic breakdown there Chris !!

Long answer short...XHTML is HTML written in XML. Two of the biggest differences are that in XHTML, anything you open must be closed, and everything must be written in lowercase. Funny how many people don't get those two.

I think xHTML is an advance version of HTML. It makes your website more w3c standard. All tags ends with </tag name>

and for tags with no closing tag like you need to make it 

note that for tags like the above, technically you don't need the space between br and the /. Works better for cross browser compatibility if you put it in there though.
