XmlSchemaInclude XmlSchemaInclude XmlSchemaInclude XmlSchemaInclude Class


Represents the include element from XML Schema as specified by the World Wide Web Consortium (W3C). This class is used to include declarations and definitions from an external schema. The included declarations and definitions are then available for processing in the containing schema.

The following XML is generated for this code example.

<?xml version="1.0" encoding="IBM437"?>
<schema elementFormDefault="qualified" targetNamespace="http://www.w3.org/2001/05/XMLInfoset" xmlns="http://www.w3.org/2001/XMLSchema">
  <import namespace="http://www.example.com/IPO" />
  <include schemaLocation="example.xsd" />


The included schema document must meet one of the following conditions:

The included schema must have the same target namespace as the containing schema document.


The included schema cannot have a specified targetNamespace; the targetNamespace attribute must be null.

XmlSchemaInclude adds all the schema components from included schemas that have the same target namespace (or no specified target namespace) to the containing schema.
