Microsoft XML Core Services (MSXML) 5.0 for Microsoft Office - XML Schemas

list

Defines a collection of a single simpleType definition.

<list
  id = ID 
  itemType = QName 
  {any attributes with non-schema Namespace}…>
Content: (annotation?, (simpleType?))
</list>

Attributes

id
The ID of this element. The id value must be of type ID and be unique within the document containing this element.

Optional.

itemType
The name of a built-in data type or simpleType element defined in this schema (or another schema indicated by the specified namespace). The simpleType element containing the list element is derived from the simple type specified by the list value. The list value must be a qualified name (QName). The use of the simpleType element child and the itemType attribute is mutually exclusive.

Not allowed if the content contains a simpleType element. Otherwise, required.

Element Information

Number of occurrences One time
Parent elements simpleType
Child elements annotation, simpleType

Remarks

When a data type is derived from a list data type, the following constraining facets can be used.

The unit of length is measured in the number of list items. For example, the following example sets the maxLength to 5, limiting the number of items in an instance of the derivedlistOfIntegers data type to 5 items in this list. Note that restrictions in a list are distinct from restrictions used in other elements.

Lists are always delimited by white space. For example, deriving a list from a simple type of three enumerations such as "books" "magazine articles" "technical newspapers and business journals" generates a list of eight strings: "books", "magazine", "articles", "technical", "newspapers", "and", "business", "journals" not a list of three strings.

Example

The following example shows a simpleType that is a list of integers where 5 is the maximum number of items allowed in the list.

<xs:simpleType name='derivedlistOfIntegers'>
  <xs:restriction base='listOfIntegers'>
    <xs:maxLength value='5'>
  </xs:restriction>
</xs:simpleType>

Example

The following example shows a simpleType that is a list of integers.

<xs:simpleType name='listOfIntegers'>
  <xs:list itemType='integer'/>
</xs:simpleType>

Example

The following example shows an instance of an element that has an attribute of type listOfIntegers. Each item in the list is of type integer and is separated by white space — in this case, a space.

<myelement listOfIntegers='1 100 9 4000 0'>
