| <h1 class="topictitle1">XML schema editor</h1> |
| <div><p>XML schemas are an XML language for describing and constraining the |
| the content of XML files.</p> |
| <p>XML schemas are a formal specification of element names that indicates |
| which elements are allowed in an XML file, and in which combinations. A schema |
| is functionally equivalent to a DTD, but is written in XML; a schema also |
| provides for extended functionality such as data typing, inheritance, and |
| presentation rules.</p> |
| <p>For more information on XML schema, refer to:</p> |
| <ul><li> <a href="http://www.w3.org/TR/xmlschema-0/" target="_blank">http://www.w3.org/TR/xmlschema-0/</a> </li> |

| <p>This product provides an XML schema editor for creating, viewing, and validating |
| XML schemas. Using the XML schema editor, you can:</p> |
| <ul><li>Create and delete XML schema components such as complex types, simple |
| types, elements, attributes, attribute groups, and groups</li> |
| <li>Edit XML schemas</li> |
| <li>Import existing XML schemas for structured viewing</li> |
| </ul> |
| <p>The XML Schema specification from the W3C Web site is used for validation.</p> |
| <div class="skipspace"><h4 class="sectiontitle">XML schema editor views - Graph, Outline, Properties, and |
| Source</h4>There are four main views you can work with in the XML schema |
| editor:<ul><li>Graph - the Graph view provides a graphical way to edit your schema</li> |
| <li>Outline - the Outline view shows you the main components in your XML schema. |
| You can use this view to add and remove certain components.</li> |
| <li>Properties - the Properties view enables you to edit the properties of |
| your XML schema components</li> |
| <li>Source - the Source view enables you to edit your source code directly</li> |
| </ul> |
| </div> |
| <div class="skipspace"><h4 class="sectiontitle">Status of the XML schema</h4><p></p> |
| <p>Three status indicators |
| for the schema are available. They are in the bottom right corner:</p> |
| <ul><li> <span class="uicontrol">Writable</span> or <span class="uicontrol">Read Only</span>. </li> |
| <li> (Source view only) <span class="uicontrol">Smart Insert</span> or <span class="uicontrol">Overwrite</span>. |
