xs:simpleType

Purpose	This element enables you to define a simple data type in the Tamino Schema Language.
Parent element	`xs:attribute`, `xs:element`, `xs:list`, `xs:schema` (only in the case of named types), `xs:union`
Child elements	`xs:list`, `xs:restriction`, `xs:union`
Attributes	`final`, `name`

Attributes

Name Type Description

Name	Type	Description
`final`		This attribute, in conjunction with the xs:schema element's `finalDefault` attribute (if the `final` attribute is not specified, the `finalDefault` attribute value takes effect), is used when performing schema checks. It specifies the methods that may be used to derive new types from the current simple type. The value is a whitespace-separated list of: restriction No type may be derived from this simple type by `restriction`. list No type may be derived from this simple type by the creation of a list type. union No type may be derived from this simple type by the creation of a union type. Alternatively, the special value "#all" prevents all methods of deriving a new type from the current simple type definition.
`name`	`xs:NCName`	For purposes of reuse, it is possible to specify a name for a simple type definition to be able to reference it later by this name. This is done with the `name` attribute of the `xs:simpleType` element. This attribute is mandatory for the definition of named simple types. For anonymous simple types, however, it must be omitted.

final

This attribute, in conjunction with the xs:schema element's finalDefault attribute (if the final attribute is not specified, the finalDefault attribute value takes effect), is used when performing schema checks. It specifies the methods that may be used to derive new types from the current simple type. The value is a whitespace-separated list of:

restriction: No type may be derived from this simple type by restriction.
list: No type may be derived from this simple type by the creation of a list type.
union: No type may be derived from this simple type by the creation of a union type.

Alternatively, the special value "#all" prevents all methods of deriving a new type from the current simple type definition.

name

xs:NCName

For purposes of reuse, it is possible to specify a name for a simple type definition to be able to reference it later by this name. This is done with the name attribute of the xs:simpleType element.

This attribute is mandatory for the definition of named simple types. For anonymous simple types, however, it must be omitted.

Example 1

This example defines a simple type based on a restriction that only the three values "instrumentalist", "jazzSinger" and "jazzComposer" are allowed for the defined type:

<xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema"
  xmlns:tsd = "http://namespaces.softwareag.com/tamino/TaminoSchemaDefinition">
 .
 .
 .
 <xs:simpleType name="role">
  <xs:restriction base = "xs:NMTOKEN">
    <xs:enumeration value = "instrumentalist"/>
    <xs:enumeration value = "jazzSinger"/>
    <xs:enumeration value = "jazzComposer"/>
  </xs:restriction>
 </xs:simpleType>
 .
 .
 .
</xs:schema>

Example 2

Here is another example showing anonymous simple type definitions:

<xs:element name = "price">
 <xs:simpleType>
   <xs:restriction base='decimal'>
     <xs:totalDigits value='9'/>
     <xs:fractionDigits value='2'/>
   </xs:restriction>
 </xs:simpleType>
</xs:element>
