OpenDocument SVG Correspondence
Section 9.2 (pp275-) of the OpenDocument specification (available at http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=office) is the most obviously related to SVG.
9.2 Drawing Shapes
draw:rect element: svg:rect (http://www.w3.org/TR/SVG11/shapes.html#RectElement)
draw:corner-radius attribute: rx. (OpenDocument has no equivalent of specifying both rx and ry, so we may forbid specifying ry in OpenDocument SVG fragments.)
draw:line element: svg:line (http://www.w3.org/TR/SVG11/shapes.html#LineElement)
draw:polyline element: svg:polyline (http://www.w3.org/TR/SVG11/shapes.html#PolylineElement)
svg:points attribute: points. The OpenDocument specification is (at first glance at least) ambiguous as to whether coordinates can contain units, whereas the SVG spec disallows units.
The OpenDocument standard allows specifying a svg:width and/or svg:height attribute, but says that these "may" be ignored. The SVG 1.1 standard does not allow specifying width or height attributes other than for rect, image, foreignObject, and a few other things (see http://www.w3.org/TR/SVG11/attindex.html).
Similarly, the OpenDocument standard allows specifying svg:x and svg:y attributes (though doesn't mention their interpretation; probably ignored); whereas the SVG 1.1 spec allows x and y attributes on only a few elements (typically those that don't otherwise specify their position).
