| <context><p>Like the <codeph>include</codeph> mechanism, <codeph>redefine</codeph> requires | |
| the external components to be in the same target namespace as the redefining | |
| schema, although external components from schemas that have no namespace can | |
| also be redefined.</p><p>The following instructions were written for the Resource | |
| perspective, but they will also work in many other perspectives.</p><p>To | |
| add a redefine element:</p></context> | |
| <steps> | |
| <step><cmd>Open your XML schema in the XML schema editor.</cmd></step> | |
| <step><cmd>In the Outline view, select your schema.</cmd><info>The entire | |
| schema and its contents are displayed in the Design view.</info></step> | |
| <step><cmd>In the Design view, right-click in the <b>Directives</b> section | |
| and click <uicontrol>Add Redefine</uicontrol>.</cmd></step> | |
| <step><cmd>In the Properties view, click the <b>General</b> tab and click <uicontrol>Browse</uicontrol> <image | |
| href="../images/Browse.gif"><alt>This graphic is the Browse button</alt></image> to | |
| <?Pub Caret?>the right of the <uicontrol>Schema location</uicontrol> field.</cmd> | |
| <info>The XML schema file you select must have the same namespace as the current | |
| schema.</info></step> | |
| <step><cmd>If you want to select an XML schema located in the workbench, select <uicontrol>Workbench | |
| projects</uicontrol> and click <uicontrol>Next.</uicontrol></cmd></step> | |
| <step><cmd>Select the schema you want to include and click <uicontrol>Finish</uicontrol>.</cmd> | |
| </step> | |
| <step><cmd>If you want to select an XML schema located on the Web, select <uicontrol>HTTP</uicontrol> and | |
| click <uicontrol>Next</uicontrol>.</cmd></step> | |
| <step><cmd>Type the URL of the XML schema and click <uicontrol>Finish</uicontrol>.</cmd> | |
| <info> <note>A local copy of the schema will not be stored in the workbench. | |
| Every time you validate your schema, the schema's contents will be checked | |
| from the URL you specify.</note></info></step> | |
| <step><cmd>The XML schema editor will retrieve the location of the included | |
| XML schema file, and display it in the <uicontrol>Schema location</uicontrol> field. | |
| This field can be edited at any time to reflect the location of the XML schema | |
| file.</cmd></step> | |
| <step><cmd>Click the <uicontrol>Documentation</uicontrol> tab if you want | |
| to provide any information about this redefine element.</cmd><info>The <uicontrol>Documentation</uicontrol> page | |
| is used for human readable material, such as a description.</info></step> | |
| <step><cmd>Click the <uicontrol>Extensions</uicontrol> tab if you want to | |
| add application information elements to your annotations of schema components.</cmd> | |
| <info>The <uicontrol>Extensions</uicontrol> page allows you to specify the | |
| schema and add XML content to your annotations.</info></step> | |
| </steps> | |
| <result><p>Once you have added the redefine element to your XML schema, you | |
| can redefine any of the simple and complex types, groups, and attribute groups | |
| in the XML schema you selected in the redefine element. </p></result> | |
