i have no idea about Springframework but here is quik diff between XML Schemas and DTDs 1. XML Schemas use XML document syntax. Declarations can have richer and more complex internal structures than declarations in DTD. XML Schemas are pure XML documents, DTDs have several limitations. 2. XML Schemas provide data-oriented data types in addition to the more document-oriented data types XML 1.0 DTDs support. 3. XML Schemas support namespaces.
I would suggest, go for XML Schema [ May 09, 2007: Message edited by: sachin poddar ]
