I actually use a variation of this technique.
I'm also working with Flash Builder for coding and Flash IDE to export
the library. The difference is that I use an implementation of this
Grant Skinner technique to get the embedded elements from my Flash
Library without losing the actionscript code. This way I don't need to
declare a class for each exported asset, neither declare its variables,
they'll all be accessible.
I'm using PureMVC, so I have a Proxy class implementing the gskinner's
technique where I just call a getSymbol() method to get each library
symbol with its linkage reference.
