        <ul>
            <li>A sevice name:</br>
                If a sequence element contains a string, this string is interpreted
                as service name, and an <type scope="com::sun::star::lang">XMultiComponentFactory</type>
                is asked to create an instance of this service.</li>
            <li>A factory:<br/>
                If a sequence element contains an instance implementing the
                <type scope="com::sun::star::lang">XSingleComponentFactory</type> interface, this factory
                is used to create a property handler.</li>
        </ul></p>

        <p>This attribute is usually only evaluated by the <type>ObjectInspector</type> instance
        which the model is currently bound to.</p>

        <p>The order of factories is important: If two property handlers declare themself responsible
        for the same property, the one whose factory is listed <strong>last</strong> wins. Also,
        if a handler <code>B</code> wants to supersede a property of another handler <code>A</code>,
        <code>A</code>'s factory must precede the factory of <code>B</code>.</p>

        Those names provided by the handlers are programmatic names. All other information

    /** retrieves an index in a global property ordering, for a given property name

        <p>In the user interface of an ObjectInspector, single properties are represented by
        single lines, and those lines are displayed successively. To determine an order of
        the property lines, the inspector model can associate an "order index" with each property.
        The <type>ObjectInspector</type> will then sort the property lines in a way that they
        have the same relative ordering as the "order indexes" of their properties.</p>

        <p>Note that the concrete value the model returns for a given property does not
        matter. All what matters is that if you want a certain property <code>Foo</code>
        to be displayed after another property <code>Bar</code>, then the order index
        of <code>Foo</code> should be greater than the order index of <code>Bar</code>.

        <p>If for two different properties the same order index is returned, the
        <type>ObjectInspector</type> will assume the order in which those properties
        were provided by the respective property handler
        (<member>XPropertyHandler::getSupportedProperties</member>).<br/>
        If two such properties originate from different handlers, they will be ordered according
        to the order of the handlers, as provided in the <member>HandlerFactories</member> attribute.</p>
