It was always intended      for web pages, books, scholarly articles, poems, short stories,      reference manuals, tutorials, texts, legal pleadings, contracts,      instruction sheets, and other documents that human beings would      read. Its use as a syntax for computer data in applications like      syndication, order processing, object serialization, database      exchange and backup, electronic data interchange, and so forth is      mostly a happy accident.   </para>      <sect1>     <title>SGML's Legacy</title>     <para></para>   </sect1>   <sect1>     <title>TEI</title>     <para></para>   </sect1>   <sect1>     <title>DocBook</title>     <para>       <ulink url="http://www.oasis-open.org/docbook/">DocBook</ulink>        is an SGML application designed for new documents, not old ones.        It's especially common in computer documentation.
