Much better. Much more concise.
Where would the preset name go? In some tag at the top?

I think that since the connection is one way, you would only need to save
one side. The connection is one way right?

I'm still not sure what you want me to do. As far as I can tell, all it
needs is a parser and then it needs to be hooked into Ardour. Writing the
parser should be easy, there must be a YACC of some kind for DTDs. Or did
you want an engine which used the parser and spits out a pointer to a
plugin network?

Each plugin is given a unique number. It's handed down by the LADSPA
cabal, I think.
