/** 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>

    </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 <method scope="com::sun::star::lang">XMultiServiceFactory::createInstanceWithArguments()</method> 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 scope="com::sun::star::lang">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>
