Schema difference

[Mike Jenkins]

In Tomcat 6 they changed web.xml to a schema.
What is the difference between a schema version of web.xml in Tomcat 6
and a non schmea version of web.xml like the one they used in 4.1.27?

Actually it's a change in the Servlet Specification, not Tomcat.

The change from Servlets 2.3 to 2.4 mandated the change from a DTD to XML Schema.

Thanks,
The difference is the beginning part of my web.xml?

DTD?
<?xml version="1.0"?>
<!DOCTYPE note [
  <!ELEMENT note (to,from,heading,body)>
  <!ELEMENT to      (#PCDATA)>
  <!ELEMENT from    (#PCDATA)>
  <!ELEMENT heading (#PCDATA)>
  <!ELEMENT body    (#PCDATA)>
]>
.....

xml?

<?xml version="1.0" encoding="ISO-8859-1" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
....
