    • The organization of RELAX
    • About this tutorial
  • Summary
• STEP 1: Migration from XML DTD (without parameter entities)
  • An example module
  • The module element
  • The interface element
    • The export element
  • Element type declarations
    • Element hedge model
      • The empty element
      • The ref element
      • The choice element
      • The sequence element
      • The none element
    • Datatype reference
    • Mixed hedge model
  • Attribute-list declarations
  • Summary
• STEP 2: Migration from XML DTD (with parameter entities)
  • Parameter entities used in content models
    • Overview
    • Permissible hedge models
    • The occurs attribute
    • Occurrence order of hedgeRef and hedgeRule
    • Illegal reference to itself
    • Use of empty
    • Use of none
  • Parameter entities used in attribute-list declarations
    • Overview
    • Occurrence order of ref and attPool
    • Multiple ref elements
    • Illegal reference to itself
  • Summary
• STEP 3: Datatypes
  • Datatypes of XML Schema Part 2
  • Datatypes unique to RELAX
    • none
    • emptyString

    • elementRule
    • attribute
  • Summary
• STEP 4: Annotation

  • Why divide modules?
  • The include element
  • Non-empty interface elements
  • Summary
• STEP 6: Default values, entities, and notations
  • Reasons that RELAX does not handle them
  • Using DTD and RELAX together
  • Better leave them out
  • Summary
• STEP 7: elementRule and hedgeRule, revisited
  • elementRule and labels
    • Context-sensitive content models
    • The label attribute of elementRule elements
    • The label attribute of ref elements
  • Sharing labels
    • Multiple hedgeRule elements sharing the same label
    • Prohibition of label sharing by hedgeRule and elementRule
    • Multiple elementRule elements sharing the same label
  • Summary
• STEP 8: tag and attPool, revisited
  • The role attribute of tag elements
    • Switching content models depending on attribute values
    • Constraints represented by tag elements
    • The role attribute of elementRule elements
    • Prohibition of references by ref elements
    • The none datatype, revisited
  • attPool elements
    • Constraints represented by attPool
    • Prohibition of references by elementRule elements
  • Prohibition of role sharing by multiple tag or attPool elements
  • Summary
• STEP 9: Hedge content model element
  • Simulating programming languages and database languages
  • The element element
  • Expansion to ref, elementRule, and tag elements
  • Expansion procedure
