Why DTDs Not Schemas? — Social

(More important than technical rationale)

• Target user community
  • Journal Publishers (STM, society, all journal)
  • Aggregators and Repositories
  • Conversion vendors

  • XML DTDs (almost never schemas)
  • SGML DTDs (still a large minority)
  • XML tools that do not support all schema formats
  • Word processors
