When saving I get the following error when validating the saved document.

content.xml:8:419: error: bad value for attribute "vertical-segments" from namespace "urn:oasis:names:tc:opendocument:xmlns:dr3d:1.0"
content.xml:46:205: error: required attributes missing
content.xml:47:205: error: required attributes missing

The value for vertical-segments has a % at the end which should not be there.
The draw:rotate miss the svg:viewBox attribute which is mandetory.

I think the code should not be committed before roundtripping to LO/OO does not work as this is the only thing it tries to archive up to now.

    I think that is a bad descition as when the layers where implemented we made the explicit design decision that we use hierarchy for the shapes and when a layer does not match the parent we fix that during loading.
    If it is only for having style information available I think it is much easier to reuse only the style loading code and don't inherit the shapes as shape are also painted by the shape manager but I'm not sure that is wanted here.

    saveOdf2 is a very bad name in my oppinion. How about using saveObjectOdf?

This makes OOo/LO not show the shapes when they are loaded again after a roundtrip through Karbon. I have not been able to analyze why Karbon saves back all shapes with layer="" when the infile clearly has layer="layout".
