Using an XML data format will work for certain sections, such as vectors and
configuration, but ultimately that is it. You can't describe an image with
full XML describing the individual pixels/strokes; the size of the XML tags
alone would be enormous for a 1024x768 image.

So you end up dumping binary blobs into the XML. That's not such a bad
things, really... You'd end up with something like:

<Krita Image>
    <Config>
        <Width value="x" />
        <Height value="y" />
        <Colour model="RGB" />
    </Config>
<Bitmap Layer>
    <Z value="z" />
    <Merging>
        <Opacity value="o%" />
        <Mapping value="Normal" />
    </Merging>
    <Data>
            ****BLOB****
    </Data>
</Bitmap Layer>
<Bitmap Layer>
.
.
</Bitmap Layer>
<Vector>
    <Vector Layer>
        <Z value="z" />
        <Merging>
            <Opacity value="o%" />
            <Mapping value="Normal" />
        </Merging>
    </Vector Layer>
    <Type value="Circle">
    <Center xvalue="xc" yvalue = "yc">
    <Radius = "r">
    <Drawing fillcolour="rgb" fill="yes" strokewidth="sw" stroke="yes"
strokecolour="rgb">
</Vector>
</Krita Image>

But it wouldn't be very sane to be purely XML for anything else than a
vector package.
