Which reminds me, I started on defining an XML representation of dot
files and wrote a PerlSAX handler that writes out real .dot files.
Very useful for generating graphs with XSLT.
I added lexical scoping for default attributes, but subgraphs need some
more thinking.

Contact me if anyone's interested, I may even rewrite it in Java to make
it useful for a larger number of people.

Example:

    <digraph id="graph0">
        <graph_attr center="1">
            <node id="node01" color="red"/>
            <node_attr shape="box">
                <node id="node02"/>
            </node_attr>
            <edge_attr dir="both">
                <edge from="node01" to="node03"/>
            </edge_attr>
            <edge from="node01" to="node02"/>
        </graph_attr>
    </digraph>
