True.  But there's no need to spell *everything* out is there?  Surely a
point in the right direction is better than a 'cut and paste' in the
long run...

I recognise the element names and have worked on this kind of dtd for a

quite spell them out :)

I still stand by using variables in this situation, they really help
maintaining and debugging the process involved.
