SOAP and DTDs

Hi John,

Something interesting I just came across in "Building Web Services with Java":

"Simple Object Access Protocol (SOAP) ... explicitly forbids the use of DTDs for defining document structure"

They also say that

"data-oriented XML applications have moved away from DTDs; these applications use another mechanism to validate XML documents and to enforce document structure and datatype rules. To address the problems inherent in DTDs, the XML community developed XML Schema.."

Something to consider for THREDDS catalogs..

- Joe
