show-end-of-presentation-slide proposal

Some presentation software implementations (including OoImpress and KPresenter)
have the feature of showing a slide at the end of the presentation saying something like
"presentation is finished, click to exit".

This feature is apparently optional in both implementations, but the setting for
enabling or disabling that feature isn't part of the OpenDocument XML.
A logical place for it would be the <presentation:settings> element.
So I suggest the following RelaxNG schema addition:

<define name="presentation-settings-attlist" combine="interleave">
    <optional>
        <attribute name="presentation:show-end-of-presentation-slide" a:defaultValue="false">
            <ref name="boolean"/>
        </attribute>
    </optional>
</define>
