MORE INFORMATION
With Document Type Definitions (DTDs), you can write
markup rules that describe the structure of XML documents and that you can use to
validate the structure of those documents. When XML 1.0 was originally
specified, the DTD syntax (which is not XML-based) was inherited mainly from
earlier markup languages, such as SGML and HTML.
DTDs do not support
XML namespaces well. The process by which DTDs are parsed does not enforce
adherence to a namespace. As an alternative to DTDs, you can describe the XML
document structure by using the World Wide Web Consortium (W3C) XML Schema language. This language offers the same
benefits as DTDs, but also resolves some of the limitations of DTDs. DTDs are
mainly useful when you are working with older XML applications that require
DTDs and do not support XML schemas.
In some cases, you may want to
reject XML messages that contain DTDs. For example, the SOAP 1.1 specification
states that a SOAP message must not contain a DTD. Therefore, a SOAP processor
can reject any SOAP message that contains a DTD. This update causes XML Web
services that are built by using the SOAP Toolkit to reject the processing of XML messages
that contain Document Type Definitions (DTDs).

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.

didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
