While trying to diagnose a problem during development, our project team ran into the BizTalk 2004 bug described in knowledge base article 891447: "FIX: A distinguished field returns incorrect content when you use the empty element tag form for the empty field in BizTalk Server 2004"

Pretty nasty bug if you're using Distinguished Fields in your orquestrations. In our case, we where using them to populate a new message that was then sent to a different application, so it kept getting the wrong content and it was not evident why!

Let's hope this makes it into SP2 (if one is planned, I don't know)...
