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

Parent elements: schema

Syntax

<include
id=ID
schemaLocation=anyURI
any attributes
>

(annotation?)

</include>

(The ? sign declares that the element can occur zero or one time inside the include element)

Attribute	Description
id	Optional. Specifies a unique ID for the element
schemaLocation	Required. Specifies the URI to the schema to include in the target namespace of the containing schema
any attributes	Optional. Specifies any other attributes with non-schema namespace

Example 1

With included schemas, the included files must all reference the same target namespace. If the schema target namespace don't match, the include won't work:

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="https://www.w3schools.com/schema">

<xs:include schemaLocation="https://www.w3schools.com/xml/customer.xsd"/>
<xs:include schemaLocation="https://www.w3schools.com/xml/company.xsd"/>

..

</xs:schema>
