Really? What do you have to add? I suspect you exaggerate a bit.

You have to declare the entities. Otherwise, you run across &frump; and 
don't know what it means. That's what DTDs are for.

You can. Of course, your various processors have to know what the various 
namespaces *mean*, so you have to declare them and you have to have a 
processor that understands them (which is where the DTDs come in).
