are DTDs still used to conform xml?

Question

From what I understand, xml schema has replaced DTDs. Does this mean that it is now outdated and should not be used? I have tried looking at different blogs but could not find anything.

Answer 1

DTDs are still usable, they work as well as they ever did. Some people love them, some people hate them. In the world of international information standards more people are using XSD these days (it has better support for defining fields such as numbers and dates), but for document design, there are lots of enthusiasts who prefer to do things the old way.
