_DEFAULT_ link and node are built-in - the default defaults
All others are initially empty, with just a reference to the parent.


Per node:
    list of properties
    for each:
        name
        value
        config filename (if any)
        config line number (if any)
        type? (so we can use a standard parser/writer)
    special name/type for comments

editor has set/get functions to alter the config.
all map fns need to use the getter to get config info
seperate array of nodes and links (as now) for *runtime* info
 - e.g. the width of the image, the calculated position, the ReadData results    
 - also store some kind of reference to the appropriate place in the DOM

To avoid PHP4 reference rubbish, each DOM item is just stored in an array with a UID. The UID is used as a reference whenever one is needed. No circular references, no accidental pass-by-value. Use uniqid().

WriteConfig then just enumerates the DOM.

Maybe need a function to optimise the tree, making sure that the property value doesn't match the parent's value (i.e. it's redundant)
