i meant, that you first should parse the whole XML-domtree and 
afterwards create the objects and connect them (when you already know 
what is there)

well, i really don't care...

hmm yes; probably make the connect-ID optional (so you _could_ name it 
and delete it as such or choose to delete it based on the object)

the advantages i really don't know, it was just an idea, as i found the 
dyn-approach quite good (as far as i remember it).
but probably XML-files wouldn't be the way you would go when doing 
dynamic patching - otoh why not ? you would then need to have atomic 
transactions, which isn't that bad either.
