* <oor:component-data xmlns:oor="http://openoffice.org/2001/registry" xmlns:xs="http://www.w3.org/2001/XMLSchema" oor:name="Views" oor:package="org.openoffice.Office">

* oor:type="xs:string">
* <value>V1,2,0</value>
* </prop>
* </node>
* </node>
* </node>
* 
* <CODE>Definition</CODE>
* <ul>
* <li><CODE><node oor:name="Windows"></CODE>
* represents a <CODE>Set</CODE> and is a <CODE>XNameContainer</CODE></LI>
* <li><CODE><node oor:name="SplitWindow0"></CODE>
* represents a <CODE>Group</CODE> and is a <CODE>XNameReplace</CODE></LI>
* <li><CODE><prop oor:name="Visible"></CODE>
* represents a pr<CODE></CODE>operty of the group</li>
* <li><CODE><node oor:name="UserData"></CODE>
* represents a <CODE>extensible group</CODE> and is a <CODE>XNameContainer</CODE></LI>
* <li><CODE><prop oor:name="UserItem"></CODE>

* We assume in the following examples the existence of:
* <CODE>ConfigHelper aConfig = new ConfigHelper(xMSF, "org.openoffice.Office.Views", false);</CODE>
* <ul>
* <li>If you like to insert a new <CODE>Group</CODE> into the <CODE>Set</CODE> "Windows":
* <CODE>XNameReplace xMyGroup = aConfig.getOrInsertGroup("Windows", "myGroup");</CODE>
* The method <CODE>getOrInsertGroup()</CODE> uses the
* <CODE>XSingleServiceFactory</CODE> to create the skeleton of a new group.
*
* </li>
* <li>If you like to change the property "WindowState" of "myGroup"
* of the Set "Windows"
* <CODE>aConfig.updateGroupProperty(
* "Windows","myGroup", "WindowState", "952,180,244,349;1;0,0,0,0;");</CODE>
* </li>
* <li>If you like to change the property "myProp" of the extensible group
* "myExtGroup" which is an extensible group of "my2ndGroup" of the
* Set "Windows":
* <CODE>aConfig.insertOrUpdateExtensibleGroupProperty(
