 <taskbody>
 <context><p>The following instructions were written for the Resource perspective,
 but they will also work in many other perspectives.</p><p>To add a global
 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>Elements</b> section
 and click <uicontrol>Add Element</uicontrol>.</cmd></step>
 <step><cmd>In the Properties view, click the <uicontrol>General</uicontrol> tab,
 and type a new name for the global element in the <uicontrol>Name</uicontrol> field.</cmd>
 </step>
 <step><cmd>In the Properties view, you can select the attribute type from
 the predefined list in the menu next to the <uicontrol>Type</uicontrol> field.</cmd>
 <info><p>Alternatively, you can select <uicontrol>Browse</uicontrol> from
 the list for more options. </p><p>The <uicontrol>Set Type</uicontrol> dialog
 box appears, and lists all built-in and user-defined types currently available.
 You can change the <uicontrol>Scope</uicontrol> of the list by selecting one
 of the following options:<ul>
 <li><uicontrol>Workspace</uicontrol>. Lists all of the types available in
 your workspace. </li>
 <li><uicontrol>Enclosing Project</uicontrol>. Lists all of the types available
 in the project that contains your file. </li>
 <li>(Default) <uicontrol>Current Resource</uicontrol>. List all of the types
 available in your current file.</li>
 <li><uicontrol>Working Sets</uicontrol>. List all the types available within
 the selected working set.</li>
 </ul></p><p>Select the type you want in the type list, then click <uicontrol>OK</uicontrol>. </p></info>
 </step>
 <step><cmd>(Optional) Click the <uicontrol>Other</uicontrol> tab.</cmd><info>In
 this page, you can specify the following various values for the global element: </info>
 <choices>
 <choice><uicontrol>abstract</uicontrol>. Click <b>true </b>if you want the
 global element to be abstract. When a global element is declared to be abstract,
 it cannot be used in an instance document. Instead, a member of that global
 element's substitution group must appear in the instance document.</choice>
 <choice><uicontrol>block</uicontrol>. This field determines whether the global
 element may be replaced by an element derived from it.</choice>
 <choice><uicontrol>final</uicontrol>. This field determines whether this global
 element may be derived from.</choice>
 <choice><uicontrol>fixed/default</uicontrol>. Click <uicontrol>Browse</uicontrol> and
 select <uicontrol>Fixed</uicontrol> or <uicontrol>Default</uicontrol> and
 specify an appropriate value. If you select <b>Fixed</b>, the global element
 has a fixed value, which cannot be changed. If you select <b>Default</b>,
 the element has a default value.</choice>
 <choice><uicontrol>form</uicontrol>. Use this field to indicate if the appearance
 of this global element in an instance of the XML schema (an XML file associated
 with the XML schema) must be qualified by a namespace.</choice>
 <choice><uicontrol>nillable</uicontrol>. Select <b>true</b> if you do not
 want the global element to be able to have any child elements, only attributes. </choice>
 <choice><uicontrol>substitutionGroup</uicontrol>. A substitution group allows
 elements to be substituted for other elements.</choice>
 </choices>
 </step>
 <step><cmd>Click the <uicontrol>Attributes</uicontrol> tab.</cmd><info>You
 can use this page to add attributes, attribute references, attributes group
 references, and <codeph>any</codeph> attributes to your global element.</info>
 </step>
 <step><cmd>An attribute associates an attribute name with a specific type
 and value. To add an attribute, right-click in the Attributes page, and click <uicontrol>Add
 Attribute</uicontrol>.</cmd><info>You can specify the following values for
 an attribute:</info>
 <choices>
 <choice><uicontrol>fixed/default</uicontrol>. Click <uicontrol>Browse</uicontrol> and
 select <uicontrol>Fixed</uicontrol> or <uicontrol>Default</uicontrol> and
 specify an appropriate value. If you select <b>Fixed</b>, the attribute has
 a fixed value, which cannot be changed. If you select <b>Default</b>, the
 attribute has a default value.</choice>
 <choice><uicontrol>form</uicontrol>. Use this field to indicate if the appearance
 of this attribute in an instance of the XML schema must be qualified by a
 namespace.</choice>
 <choice><uicontrol>name</uicontrol>. Enter the name of the attribute.</choice>
 <choice><uicontrol>type</uicontrol>. Click <uicontrol>Browse</uicontrol> and
 select the type of the attribute. </choice>
 <choice><uicontrol>use</uicontrol>. This field indicates how an attribute
 can be used in an instance document. If you select optional, the attribute
 can appear once, but it does not have to. If you select required, the attribute
 must appear once. If you select prohibited, the attribute must not appear. <b>Note</b>:
 If you selected <uicontrol>Default</uicontrol>, you must select <b>optional</b> in
 this field, otherwise the default value will not be valid.</choice>
 </choices>
 </step>
 <step><cmd>An attribute reference provides a reference to a global attribute.
 To add an attribute reference, right-click in the Attributes page, and click <uicontrol>Add
 Attribute Ref</uicontrol>.</cmd><info>A declaration that references a global
 attribute enables the referenced attribute to appear in the instance document
 in the context of the referencing declaration. The menu option to add an attribute
 reference only appears if there are global attributes defined elsewhere in
 the document. Select the reference, then select the global attribute you want
 it to reference from the <uicontrol>ref</uicontrol> list.</info></step>
 <step><cmd>An attribute group reference provides a reference to an attribute
 group. To add an attribute group reference, right-click in the Attributes
 page, and click <uicontrol>Add Attribute Group Ref</uicontrol>.</cmd><info>A
 declaration that references an attribute group enables the referenced attribute
 group to appear in the instance document in the context of the referencing
 declaration. The menu option to add an attribute group reference only appears
 if there are attribute groups defined elsewhere in the document. Select the
 reference, then select the attribute group you want it to reference from the <uicontrol>ref</uicontrol> list.</info>
 </step>
 <step><cmd>An <codeph>any</codeph> element enables element content according
 to namespaces, and the corresponding <codeph>any</codeph> attribute element
 enables attributes to appear in elements. To add an <codeph>any</codeph> attribute,
 right-click in the Attributes page and click <uicontrol>Add Any Attribute</uicontrol>.</cmd>
 <info>You can specify the following values for an <codeph>any</codeph> attribute:</info>
 <choices>
 <choice>For a <uicontrol>namespace</uicontrol> value, you can
 select:<ul>
 <li><b>##any</b>. This allows any well-formed XML from any namespace.</li>
 <li><b>##local </b>. This allows any well-formed XML that is not declared
 to be in a namespace.</li>
 <li><b>##other</b>. This allows any well-formed XML that is not from the target
 namespace of the type being defined.</li>
 <li><b>##targetNamespace </b>. This is shorthand for the target namespace
 of the type being defined.</li>
 </ul></choice>
 <choice>For a <uicontrol>processContents</uicontrol> value, you can select:<ul>
 <li><b>skip</b>. The XML processor will not validate the attribute content
 at all.</li>
 <li><b>lax</b>. The XML processor will validate the attribute content as much
 as it can.</li>
 <li><b>strict</b>. The XML processor will validate all the attribute content.</li>
 </ul></choice>
 </choices>
 </step>
 <step><cmd>Click the <uicontrol>Documentation</uicontrol> tab if you want
 to provide any information about this global 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>
 <postreq>You can add a content model to a global element, which is the representation
 of any data that can be contained inside the global element. For more information
