SPEC: line style for footnote separator (14.2.20)

The footnote separator currently has the following attributes:
width, rel-width, color, adjustement, and distance before/after.

It seems to be lacking a line style attribute, in order to have a dotted
or dashed line, which at least KWord has (or does this make no sense?).

<define name="style-footnote-sep-attlist" combine="interleave">
    <optional>
        <attribute name="style:footnote-sep-style">
            <ref name="lineStyle"/>
        </attribute>
    </optional>
</define>
