 <h1 class="topictitle1">Adding attribute groups</h1>


 <div><p>An attribute group definition is an association between
 a name and a set of attribute declarations. Named groups of attribute
 declarations can greatly facilitate the maintenance and reuse of common
 attribute declarations in an XML schema.</p>

 <div class="section"><p>The following instructions were written for the Resource
 perspective, but they will also work in many other perspectives.</p>
 <p>To
 add an attribute group to an XML schema, complete the following steps:</p>
 </div>

 <ol>
 <li class="stepexpand"><span>Open your XML schema in the XML schema editor.</span></li>

 <li class="stepexpand"><span>In the Outline view, right-click the <span class="uicontrol">Attributes</span> folder
 and click  <span class="uicontrol">Add Attribute Group</span>. </span> It
 appears in the <span class="uicontrol">Attributes</span> folder.</li>

 <li class="stepexpand"><span>Select your new group, and in the Design view, right-click
 the attribute group and select <span class="menucascade"><span class="uicontrol">Refactor</span>
  &gt; <span class="uicontrol">Rename</span></span>. In the <span class="uicontrol">New
 Name</span> field, type a name for the attribute group and click <span class="uicontrol">OK</span>.</span>
 </li>

 <li class="stepexpand"><span>To add an attribute, right-click your attribute group in
 the Outline view, click <span class="uicontrol">Add Attribute</span>. </span>
  The attribute appears below the attribute group in the Outline
 view.
 <ol type="a">
 <li class="substepexpand"><span>Select the attribute, and in the Design view, click
 the current (default) name of the attribute, then type the new <span class="uicontrol">Name</span>.</span>
 </li>

 <li class="substepexpand"><span>In the Design view, click the current (default) attribute
 type and select a type from the menu. Alternately, you can select
 browse to invoke the Set Type menu for more options. </span> The
 Set Type dialog lists all built-in and user-defined types currently
 available. You can change the <span class="uicontrol">Scope</span> of the
 list by selecting one of the following options:<ul>
 <li><span class="uicontrol">Workspace</span>. Lists all of the types available
 in your workspace. </li>

 <li><span class="uicontrol">Enclosing Project</span>. Lists all of the types
 available in the project that contains your file. </li>

 <li><span class="uicontrol">Current Resource</span> (default). List all of
 the types available in your current file.</li>

 <li><span class="uicontrol">Working Sets</span>. List all the types available
 within the selected working set.</li>

 </ul>
 </li>

 </ol>

 </li>

 <li class="stepexpand"><span>An attribute reference provides a reference to a global
 attribute. To add an attribute reference, in the Design view, right-click
 the complex type containing the element, and click <span class="uicontrol">Add
 Attribute Ref</span>. </span> A declaration that references
 a global attribute enables the referenced attribute to appear in the
 instance document in the context of the referencing declaration. Select
 the reference, then in the Properties view, select the attribute you
 want it to reference from the <span class="uicontrol">Reference</span> list.</li>

 <li class="stepexpand"><span>An attribute group reference provides a reference to an
 attribute group. To add an attribute group reference, in the Design
 view, right-click the complex type containing the element, and click <span class="uicontrol">Add
 Attribute Group Ref</span>. </span> A declaration that references
 a global attribute enables the referenced attribute to appear in the
 instance document in the context of the referencing declaration. Select
 the reference, then in the Properties view, select the attribute group
 you want it to reference from the <span class="uicontrol">Reference</span> list.
 </li>

 <li class="stepexpand"><span>An <samp class="codeph">any</samp> element enables element content
 according to namespaces, and the corresponding <samp class="codeph">any</samp> attribute
 element enables attributes to appear in elements. To add an <samp class="codeph">any</samp> attribute,
 right-click your attribute group and click <span class="uicontrol">Add Any Attribute</span>. </span>
  The <samp class="codeph">any</samp> appears below the attribute group in
 the Outline view. You can specify the following values for an <samp class="codeph">any</samp> attribute:
 <ul>
 <li>For a <span class="uicontrol">Namespace</span> value, you can select:<ul>
 <li><strong>##any</strong>: this allows any well-formed XML from any namespace.</li>

 <li><strong>##local </strong>: this allows any well-formed XML that is not declared
 to be in a namespace.</li>

 <li><strong>##other</strong>: this allows any well-formed XML that is not from
 the target namespace of the type being defined.</li>

 <li><strong>##targetNamespace </strong>: this is shorthand for the target namespace
 of the type being defined.</li>

 </ul>
 </li>

 <li>For a <span class="uicontrol">Process Contents</span> value, you can
 select:<ul>
 <li><strong>skip</strong>: the XML processor will not validate the attribute
 content at all.</li>

 <li><strong>lax</strong>: the XML processor will validate the attribute content
 as much as it can.</li>

 <li><strong>strict</strong>: the XML processor will validate all the attribute
 content.</li>

 </ul>
 </li>

 </ul>

 </li>

 </ol>
