Ok sorry you wanted to cover market data...
tackle Fplm and leave mxml as student exercise. Is mxml schema copyrighted?

since Murex is not too enthusiastic about this idea (for some
understandable reasons, I think) I guess it is not advisable to start
this as a public project. We could still do it with a ql-proprietary
format and leave MX specific extensions to private projects, but I
don't find that very attractive to be honest. Anyway.

Peter
