 information about its encoding.  Then the rest of the document is a text
 format whose structure is specified by tags between brackets. <strong>Each
 tag opened has to be closed</strong>. XML is pedantic about this. However, if
 a tag is empty (no content), a single tag can serve as both the opening and
 closing tag if it ends with <code>/&gt;</code> rather than with
 <code>&gt;</code>. Note that, for example, the image tag has no content (just
-an attribute) and is closed by ending the tag with <code>/&gt;</code>.</p>
