Then the document is a text format whose 102structure is specified by tags between brackets. <strong>Each tag opened has 103to be closed</strong>. XML is pedantic about this. However, if a tag is empty 104(no content), a single tag can serve as both the opening and closing tag if 105it ends with <code>/></code> rather than with <code>></code>. Note 106that, for example, the image tag has no content (just an attribute) and is 107closed by ending the tag with <code>/></code>.</p> 108<p>XML can be applied sucessfully to a wide range of uses, from long term 109structured document maintenance (where it follows the steps of SGML) to 110simple data encoding mechanisms like configuration file formatting (glade), 111spreadsheets (gnumeric), or even shorter lived documents such as WebDAV where 112it is used to encode remote calls between a client and a server.</p> 113<p><a href="mailto:daniel@veillard.com">Daniel Veillard</a></p> 114</td></tr></table></td></tr></table></td></tr></table></td> 115</tr></table></td></tr></table> 116</body> 117</html> 118
