Other Solutions to Typing:
Constructor Functions

type-name("value")

• These are implied functions (because defined in another spec)
• Requires the namespace! xmlns:xs="http://www.w3.org/2001/XMLSchema"
• There is one for every atomic type (XSD data types)
• Converts other atomic types into the type named
• The name of the function is the same as the name of the type
  (including namespace!)
• Acts like a “cast as” function
• For example
  xs:date("2005-08-30")
  Acts the same as ("2005-08-30" cast as xs:date)
