This version aims to improve the handling queue bundling and fix a few other things as well. Queue bundling still doesn't work quite the same way as the Perl converter. Especially in the handling of the final "target" of the 3 item queue bundle, which is more or less entirely ignored by this current converter. It may eventually be handled, but it depends on whether it was ever necessary to begin with or if it was just a necessary artifact which the Perl converter needed but isn't needed in C# using System.Xml.Linq.
