That would do. But there there has to be a possibility for multiline
input. Defining a primitive could be much larger than regular 80
characters and in one line it become unreadable. So one shall be
allowed to split let say defining parameters and operations to several
lines.

It doesn't allow to define it but cibadmin refuses to accept it
without intervals complaining that it doesn't conform to DTD. That's
why I have it in my xml file.
