Attribute Description
id Optional. Specifies a unique ID for the element
attributeFormDefault Optional. The form for attributes declared in the target namespace of this schema. The value must be "qualified" or "unqualified". Default is "unqualified". "unqualified" indicates that attributes from the target namespace are not required to be qualified with the namespace prefix. "qualified" indicates that attributes from the target namespace must be qualified with the namespace prefix
elementFormDefault Optional. The form for elements declared in the target namespace of this schema. The value must be "qualified" or "unqualified". Default is "unqualified". "unqualified" indicates that elements from the target namespace are not required to be qualified with the namespace prefix. "qualified" indicates that elements from the target namespace must be qualified with the namespace prefix
blockDefault Optional. Specifies the default value of the block attribute on element and complexType elements in the target namespace. The block attribute prevents a complex type (or element) that has a specified type of derivation from being used in place of this complex type. This value can contain #all or a list that is a subset of extension, restriction, or substitution:
  • extension - prevents complex types derived by extension
  • restriction - prevents complex types derived by restriction
  • substitution - prevents substitution of elements
  • #all - prevents all derived complex types
finalDefault Optional. Specifies the default value of the final attribute on element, simpleType, and complexType elements in the target namespace. The final attribute prevents a specified type of derivation of an element, simpleType, or complexType element. For element and complexType elements, this value can contain #all or a list that is a subset of extension or restriction. For simpleType elements, this value can additionally contain list and union:
  • extension - prevents derivation by extension
  • restriction - prevents derivation by restriction
  • list - prevents derivation by list
  • union - prevents derivation by union
  • #all - prevents all derivation
targetNamespace Optional. A URI reference of the namespace of this schema
version Optional. Specifies the version of the schema
xmlns A URI reference that specifies one or more namespaces for use in this schema. If no prefix is assigned, the schema components of the namespace can be used with unqualified references
any attributes Optional. Specifies any other attributes with non-schema namespace
