Many in the "document-centric" (as opposed to "data-centric") XML community have been skeptical about thevalue of XML Schema for publishing-oriented XML applications. Many in the community believe that XML Schema,given its complexity as compared to XML DTDs, is of questionable value for supporting XML-based publishing applications. For example, although XML Schema offers far richer data typing than do XML DTDs, many consider the datatyping capabilities of DTDs to be "good enough" for XML-based publishing applications. The XML Schema Recommendation has significant value for XML-based publishing applications. This paper provides an overview of the benefits of XML Schema over XML DTDs for those applications, and addresses real and perceived disadvantages of XML Schema over XML DTDs.
