XML Schema include element
Definition and usage
The include element is used to add multiple schemas with the same target namespace to a document.
Element information
| Occurrence | Unrestricted |
| Parent element | schema |
| Content | annotation |
Syntax
<include id=ID schemaLocation=anyURI any attributes > (annotation?) </include>
| Attributes | Description |
|---|---|
| id | Optional. Specifies the unique ID of the element. |
| schemaLocation | Required. Specifies the URI of the schema to be included in the target namespace where the schema is included. |
| any attributes | Optional. Specifies any other attributes with a non-schema namespace. |
(? The symbol declaration is in the include element, which can appear zero or once.)
Instance
Through the included schema, all included files must refer to the same target namespace. If the schema target namespace does not match, the inclusion will not be valid:
<?xml version="1.0"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.codew3c.com/schema" <xs:include schemaLocation="http://www.codew3c.com/schema/customer.xsd"/> <xs:include schemaLocation="http://www.codew3c.com/schema/company.xsd"/> .. .. .. </xs:schema>
