  • Thread-topic: [xml-dev] XSD spec question

  Can anybody please explain me the real difference between XSD and DTD. Because both are used to define the schema of an XML document.
Whereas DTD is more powerful in the sense that XML parser can cross validate an XML document based on its DTD, and this is really useful in business world as XML is mostly used to exchange the data between parties.
On the other hand XSD defines the schema in XML syntax only which is more readable, but XML parser CAN NOT cross validate one XML document based on a given XSD.
Then I am not understanding why people go for XSD ?
Can some body correct me please !
Thanks in advance,
Rabindra Nath Saha
