###### Examples:

        <provider
            extensions=".jav"
            class="org.eclipse.ui.examples.javaeditor.JavaDocumentProvider"
            id="org.eclipse.ui.examples.javaeditor.JavaDocumentProvider">
        </provider>
    </extension>

This example registers `org.eclipse.ui.examples.javaeditor.JavaDocumentProvider` as the default provider for files with the extension ".jav".

    <extension point="org.eclipse.gmf.runtime.diagram.ui.resources.editor.documentProviders">
        <provider
            inputTypes="org.eclipse.ui.IStorageEditorInput"
            class="org.eclipse.gmf.runtime.diagram.ui.resources.editor.FileDocumentProvider"
            id="org.eclipse.gmf.runtime.diagram.ui.resources.editor.FileDocumentProvider">
        </provider>
    </extension>

This example registers `org.eclipse.gmf.runtime.diagram.ui.resources.editor.FileDocumentProvider` as the default provider for all editor inputs that are `instance of org.eclipse.ui.IStorageEditorInput`.
