Name

xs:sequence(outside a group) — Compositor to define an ordered group of elements.

Synopsis

<xs:sequence
           id                 = xs:ID
           maxOccurs          = ( xs:nonNegativeInteger | “unbounded” ) : “1”
           minOccurs          = xs:nonNegativeInteger : “1”
           {any attributes with non-schema namespace}
           >
           Content: (xs:annotation?, (xs:element | xs:group | xs:choice |
                      xs:sequence | xs:any) )*)
</xs:sequence>

May be included in: xs:choice (outside a group), xs:choice (within a group), xs:complexType (local definition), xs:complexType (global definition), xs:extension (complex content), xs:restriction (complex content), xs:sequence (within a group), xs:sequence (outside a group)

Description

This compositor is used to define an ordered list or set of elements. It can hold its own minOccurs and maxOccurs attributes to define a number of occurrences of the whole sequence.

Restrictions

xs:sequence may not be included in an xs:all compositor, and xs:sequence may not include xs:all compositors.

When xs:sequence is included in an xs:group compositor, its content model is slightly different (see xs:sequence(within a group) (within a group)).

Example

<xs:element name="library">
  <xs:complexType>
    <xs:sequence>
      <xs:element ref="book" maxOccurs="unbounded"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

Attributes

id

W3C XML Schema’s element ID.

maxOccurs

Maximum number of occurrences.

minOccurs

Minimum number of occurrences.
