Giving Some Depth to Our First Schema Working From the Structure of the Instance Document New Lessons 4. Using Predefined Simple Datatypes Lexical and Value Spaces Whitespace Processing String Da tatypes Numeric Datatypes Date and Time Datatypes List Types What About anySimpleType? Back to Our Library 5. Creating Simple Datatypes Derivation By Restrict ion Derivation By List Derivation By Union Some Oddities of Simple Types Back to Our Library 6. Using Regular Expressions to Specify Simple Datatypes The Swiss Army Knife The Simplest Possible Patterns Quantifying More Atoms Common Patterns Back to Our Library 7. Creating Complex Datatypes Simple Versus Complex Types Examining the Landscape Simple Content Models Complex Content Models Mixed Content Models Empty Content Models Back to Our Library Derivation or Groups 8. Creating Building Blocks Schema Inclusion Schema Inclusion with Redefinition Other Alternatives Simplifying the Library 9. Defining Uniqueness, Keys, and Key References xs :ID and xs:IDREF XPath-Based Identity Checks ID/IDREF Versus xs:key/xs:keyref Using xs:key a nd xs:unique As Co-occurrence Constraints 10 Controlling Namespaces Namespaces Present Two Challenges to Schema Languages Namespace Declarations To Qualify Or Not to Qualify? Disruptive Attributes Namespaces and XPath Expressions Referencing Other Namespaces Schemas for XML, XML Base and X Link Namespace Behaviour of Imported Components Importing Schemas with No Namespaces Chameleon Design Allowing Any Elements or Attributes from a Particular Namespace 11. Referencing Schemas and Schema Datatypes in XML Documents Associating Schemas with Instance Documents Defining Element Types Defining Nil (Null) Values Beware the Intrusive Nature of These Features 12. Creating More Building Blocks Using Object-Oriented Features Substitution Groups Controlling Derivations 13. Creating Extensible Schemas Extensible Schemas The Need for Open Schemas 14.
