| <h1 class="topictitle1">Editing XML schema properties</h1> |
| <div><p>After you create an XML schema, you can edit its various properties, |
| such as its namespace and prefix.</p><div class="skipspace"><p>The following |
| instructions were written for the Resource perspective, but they will |
| also work in many other perspectives.</p> |
| <p>To edit an XML schema's |
| properties follow these steps:</p> |
| </div> |
| <ol><li class="skipspace"><span>Create a new XML schema or double-click an existing schema in the |
| Navigator view.</span> It will automatically open in the XML schema editor.</li> |
| <li class="skipspace"><span>In the Properties view, click the <b> <span class="uicontrol">General</span></b> tab.</span></li> |
| <li class="skipspace"><span>You can change the <b> <span class="uicontrol">Prefix</span></b> associated with |
| the current namespace.</span> Element and attribute names that are associated |
| with this namespace will be prefixed with this value.</li> |
| <li class="skipspace"><span>You can also edit the <b> <span class="uicontrol">Target namespace</span> |
| </b>for |
| this schema.</span> A namespace is a URI that provides a unique name |
| to associate with all the elements and type definitions in a schema.<ol type="a"><li><span>Click |
| <b> <span class="uicontrol">Advanced</span></b> if you want to add more |
| namespace declarations to your XML schema.</span></li> |
| </ol> |
| </li> |
| <li class="skipspace"><span>Click the <b> <span class="uicontrol">Other</span></b> tab.</span> You can |
| modify the following values in this page.<ol type="a"><li class="skipspace"><span>The |
| <b> <span class="uicontrol">attributeFormDefault</span></b> value. </span> Select |
| <b> <span class="uicontrol">qualified</span></b> if you want attributes in an |
| XML schema instance to be qualified by the prefix that is associated with |
| the schema namespace; otherwise, select <b> <span class="uicontrol">unqualified</span></b>.</li> |
| <li class="skipspace"><span>The <b> <span class="uicontrol">blockDefault</span></b> value.</span> This |
| field determines whether the types or elements in the schema may be replaced |
| by elements or types derived from them. The effect of specifying the |
| blockDefault attribute is equivalent to specifying a block attribute on every |
| type definition and element declaration in the schema. You can either select |
| <strong>#all</strong> (nothing may be replaced by derivations),<strong> |
| extension</strong> (nothing may be replaced by derivations-by-extension), |
| <strong>restriction</strong> (nothing may be replaced by |
| derivations-by-restrictions ) or <strong>substitution</strong> (nothing may be |
| replaced by derivations-by-substitution). </li> |
| <li class="skipspace"><span>The <b> <span class="uicontrol">elementFormDefault</span></b> value.</span> Select <span class="uicontrol">qualified</span> if |
| you want elements in an XML schema instance to be qualified by the prefix |
| that is associated with the schema namespace; otherwise, select <span class="uicontrol">unqualified</span>.</li> |
| <li class="skipspace"><span>The <b> <span class="uicontrol">finalDefault</span></b> value.</span> This |
| field determines whether the types or elements in the schema may be derived |
| from. The effect of specifying the final default attribute is equivalent to |
| specifying a final attribute on every type definition and element declaration in |
| the schema. If you select <strong>#all</strong>, no types or elements in the |
| schema may be derived from. If you select <strong>extension</strong>, no types |
| or elements in the schema may be derived from using extension. If you select |
| <strong>restriction</strong>, no types or elements in the schema may be derived |
| from using restriction. </li> |
| <li class="skipspace"><span>The <b> <span class="uicontrol">version</span></b> |
| value.</span> Type the version number of the schema in the <b> <span class="uicontrol"> |
| version</span></b> field.</li> |
| <li class="skipspace"><span>The <b> <span class="uicontrol">xml:lang</span> </b>value. </span> Type |
| the appropriate ISO-IETF (for example, en-us) tag in this field. This tag |
| may be inserted in documents to specify the language used in the contents |
| and attribute values of any element in an XML file.</li> |
| </ol> |
| </li> |
| <li class="skipspace"><span>Click the <b> <span class="uicontrol">Documentation</span></b> tab if you want |
| to provide any information about this XML schema.</span> The <span class="uicontrol">Documentation</span> page |
| is used for human readable material, such as a description, and the <span class="uicontrol">App |
| Info</span> page can be used to provide information for applications.</li> |
