Daniel Veillard42766c02002-08-22 20:52:17 +0000[diff] [blame]24information about its encoding. Then the rest of the document is a text
25format whose structure is specified by tags between brackets. <strong>Each
26tag opened has to be closed</strong>. XML is pedantic about this. However, if
27a tag is empty (no content), a single tag can serve as both the opening and
28closing tag if it ends with <code>/&gt;</code> rather than with
29<code>&gt;</code>. Note that, for example, the image tag has no content (just
