// DocMerge from xml: service com::sun::star::registry::NestedRegistry
/** supports a shared view on two different registries. The registry 
    files will be opened in two different modes, registry1 will be opened with read/write 
    rights and registry2 will be opened read-only.
    In the context of this service, the functions <code>open</code>, <code>close</code>, 
    and <code>destroy</code> from <type>XSimpleRegistry</type> are not supported and 
    throw an exception if they are used. 
    <dl>
    <dt>Functions of <type>XSimpleRegistry</type>:
    <dl>
    <dt>	<b>getURL</b> 
    </dt>
    <dd> returns the name of registry1.
    
    </dd>
    <dt>	<b>isValid</b> 
    </dt>
    <dd> checks if registry1 is valid. If the interface is not <NULL/>
    then registry1 should always be valid. 
    
    </dd>
    <dt>	<b>isReadOnly</b> 
    </dt>
    <dd> checks if registry1 has write protection.
    </dd>
    <dt>	<b>mergeKey</b> 
    </dt>
    <dd> merges all information from the specified registry in registry1.
    
    </dd>
    <dt>	<b>getRootKey</b> 
    </dt>
    <dd> returns a virtual rootkey of both registries.
    </dd>
    </dl>   
    
    <br>
    
    </dt>
    <dt>Functions of <type>XRegistryKey</type>:
    <dl>
    <dt> <b>openKey</b> 
    </dt>
    <dd> returns a virtual key which is specified in registy1 or registry2.
    
    </dd>
    <dt> <b>deleteKey</b> 
    </dt>
    <dd> deletes the key only if it is present in registry1.
    
    </dd>
    <dt> <b>setLongValue, setAsciiValue, setStringValue, setBinaryValue</b> 
    </dt>
    <dd> sets the value at the specified key in registry1.
    
    </dd>
    <dt> <b>getLongValue, getAsciiValue, getStringValue, getBinaryValue</b> 
    </dt>
    <dd> returns the value at the specified key in registry1, or if 
    the value is not present in registry1, it will return the value of registry2.
    
    </dd>
    <dt> <b>openKeys</b> 
    </dt>
    <dd> returns a sequence of all subkeys in both registries.
    
    </dd>
    <dt> <b>getKeyNames</b> 
    </dt>
    <dd> returns a sequence with the names of all subkeys in both 
    registries.
    
    </dd>
    <dt>
    <br>
    <b>Note: all write functions only work on registry1.</b>
    </dt>
    </dl>
    </dt>
    </dl>
    <br>
    How to initialize the registries:<br>
    Use a sequence of <type>XSimpleRegistry</type> with two elements. The first element must be 
    the registry which is opened with read/write rights and the second element must be 
    the read-only one.<br>
    Two different ways are possible:<br>
    <ul>
    <li> use <member>com.sun.star.lang.XMultiServiceFactory::createInstanceWithArguments()</member> to
    create an instance of this service where the value of the any parameter must be the sequence with
    the two open registries.
    <li> use the initialize function of the <type>XInitialization</type> interface where the value of the 
    any parameter must be the sequence with the two open registries.
    </ul>
    <br>
    
    
    Guarantees:
    <ul>
    <li>-thread safe</li>
    </ul>
