Is XML an issue for FIX? I was under the impression that XML was 
used to describe the data/messages, but not so much a requirement 
at runtime. Usually message are special character delimited 
strings, which D can do well with.

In terms of it becoming redundant, what are some of the new 
competitors to it?
