	/** This interface gives access to any text, table, graphic, embedded
	  	object and drawing that is at least partially visible on the screen.
		The tree that arises from the children of this object reflects the
		structure of the document as it is displayed.

		<ul>
			<li>The children returned by
                <method scope="::com::sun::star::accessibility"
                >XAccessibleContext::getAccessibleChild</method> all support
                the interface XAccessible. Calling
				<method scope="::com::sun::star::accessibility"
                >XAccessible::getAccessibleContext</method> for these children
                returns an object that supports one of the following
                services.
				<ul>
					<li><type scope="::com::sun::star::text"
                        >AccessibleHeaderFooterView</type>:
						A child of this kind is returned for every header
						and footer that is at least partially visible.
					<li><type scope="::com::sun::star::text"
                        >AccessibleFootnoteView</type>:
						A child of this kind is returned for every footnote
						that is at least partially visible.
					<li><type scoep="::com::sun::star::text"
                        >AccessibleEndnoteView</type>:
						A child of this kind is returned for every endnote
						that is at least partially visible.
					<li><type scope="::com::sun::star::text"
                        >AccessibleParagraphView</type>:
						A child of this kind is returned for every paragraph
						fragment that is contained in the document body and
						is at least partially visible. A paragraph fragment is
						the part of a paragraph that is displayed on a
						certain page.
					<li><type scope="::com::sun::star::table"
                        >AccessibleTableView</type>:
						A child of this kind is returned for every table
						fragment that is contained in the document body
						and is at least partially visible. A table fragment is
						the part of a table that is displayed on a certain page.
					<li><type scope="::com::sun::star::text"
                        >AccessibleTextFrameView</type>: A child of this
                        kind is returned for every text frame that is at
                        least partially visible. These objects are children
                        of the
						<type>AccessibleTextDocumentView</type> regardless
						whether they are bound to a page, a paragarph, a
						frame, or a character. The only exception are text
						frames that are bound as character. They are childen
						of the paragraph they are contained in.
					<li><type scope="::com::sun::star::text"
                        >AccessibleTextGraphicObject</type>:
						A child of this kind is returned for every graphic that
						is at least partially visible. These objects are
						children of the <type>AccessibleTextDocumentView</type>
						regardless whether they are bound to a page, paragraph,
						a frame or a character. The only exception
						are text frames that are bound as character. They are
						childen of the paragraph they are contained in.
					<li><type scope="::com::sun::star::text"
                        >AccessibleTextEmbeddedObject</type>:
						A child of this kind is returned for every embedded
						object that is at least partially visible.
						These objects are children of the
						<type>AccessibleTextDocumentView</type> regardless
						whether they are bound to a page, a paragarph, a frame,
						or a character.  They are childen of the paragraph they
						are contained in.
					<li><type scope="::com::sun::star::drawing"
                        >AccessibleShape</type>: A child of this kind (or a
                        derived interface) is returned for every shape that
                        is at least partially visible. These objects are
                        children of the
                        <type>AccessibleTextDocumentView</type> regardless
                        whether they are bound to a page, a paragraph, a
                        frame or a character.
				</ul>
				<p>The following rules apply to the children order:
				<ul>
					<li>The logical order of paragraph and table fragments is
						never changed.
					<li>Headers appear immediately before the first paragraph or
						table fragment of the header's page.
					<li>Footnotes appear immediately after the last paragraph or
						table fragment of the footnote's page. The logical order
						of footnotes isn't changed.
					<li>Endnotes appear immediately after the last footnote of
						the endnote's page or after the last paragraph or
						table fragment of this page if there are no footnotes.
						The logical order of endnotes isn't changed.
					<li>Footers appear immediately after the last endnote,
						footnote, paragraph or table fragment of the footer's
						page.
					<li>Text frames, graphics, embedded objects and shapes that
						are painted in the background appear before any other
						children. Their order reflects the z order.
					<li>Text frames, graphics, embedded objects and shapes
						that are painted in the foreground appear behind any
					   	other children. Their order reflects the z order,
						with the exception of controls that appear really last,
						but also keep the z order.
				</ul>
			<li>The role is <const scope="::com::sun::star::accessibility"
                >AccessibleRole::DOCUMENT</const>.
			<li>The name is "document view" (or the equivalent term
				in application's language).
			<li>The description also is "document view" (or the equivalent term
				in application's language).
			<li>There are no relation sets.
			<li>The following states might be contained in the state set
				returned by <method scope="::com::sun::star::accessibility"
                >XAccessibleContext::getAccessibleStateSet</method>:
				<ul>
					<li><const scope="::com::sun::star::accessibility"
                        >AccessibleStateType::DEFUNC</const> (indicates that
                        the document window has been closed)
					<li><const scope="::com::sun::star::accessibility"
                        >AccessibleStateType::EDITABLE</const>
					<li><const scope="::com::sun::star::accessibility"
                        >AccessibleStateType::ENABLED</const> (always
                        contained)

                        >AccessibleStateType::MULTI_SELECTABLE</const>
                        (always contained)
					<li><const scope="::com::sun::star::accessibility"
                        >AccessibleStateType::OPAQUE</const> (always
