 <title>Replace DTDs? Why?</title>
 <link>http://xml.sys-con.com/node/40032</link>
 <description>Of all the standards to accompany XML that are currently in progress at the W3C, few are more anxiously awaited than the Schema standard - the specification that provides an alternative to XML 1.0 DTDs as a way to describe a document&#039;s structure. But what&#039;s wrong with XML 1.0 DTDs? How many alternatives have been proposed, and by whom? Why didn&#039;t the W3C address these concerns in the original XML 1.0 specification instead of waiting until now? I&#039;ll answer those questions in this column, and in my next column we&#039;ll look at the current state of the W3C Schema Working Group&#039;s unfinished proposal.&lt;p&gt;&lt;a href=&quot;http://xml.sys-con.com/node/40032&quot; target=&quot;_blank&quot;&gt;read more&lt;/a&gt;&lt;/p&gt;</description>
