Notes

• Chameleon components - when an including schema document has a target namespace and an included schema document does not have a namespace, all components of the included schema document take on the namespace of the including document. See pg 66-67 of Definitive XML Schema.
• Use global or local element declarations? (pg 125-126, Definitive XML Schema)
  • Use global if:
    • The element decl. could ever apply to the root element during validation
    • You want to use the exact same element decl. in more than one complex type
    • You want to use the element decl. in a substitution group.
  • Use local if:
    • You want to allow unqualified element-type names in the instance.
    • You want to declare several element types with the same name but different data types or other properties.
• Should attributes be declared globally or locally? (pg 147-148, Definitive XML Schema)
  • Global attribute decl. are discouraged unless the attribute us used in a variety of element decl. which are in a variety of namespaces.
