The above declarations include the namespace prefix before each element. 
As I write in my other mails, DTDs can not deal with namespaces. So this 
is the only way to accomplish it in a more or less hacky way. :)

The parameter entity %NS.prefixed; holds INCLUDE or IGNORE depending 
whether you wish to insert a prefix or not. The PE %MATHML.prefix; 
contains the namespace prefix itself. If you scroll up a bit, you can see 
it is "mml". All these declarations is needed to put together the element 
name, either with or without the prefix.

HTH,
Tom
