This is a paragraph
XML is a markup language where everything must be marked up correctly, which results in "well-formed" documents.
XML is designed to describe data, and HTML is designed to display data.

Therefore - by combining the strengths of HTML and XML, I recommended a markup language that is useful now and in the future -Which is XHTML.
