Case 4: HTML to User-defined Structure with a DTD/Schema

• Structure is user-specific
• Document Model explicitly defines document structure, e.g.:
  • Transaction = Address-header followed by Supplier-header followed by Transaction-body
  • Document = one or more Parts; Part = one or more Chapters; Chapter = one or more Sections
• Document Type Definition (DTD) or schema used to define structure
• Document can be validated against structure
