Just about any file I came acros they have these things in there, so is 
this just overkill or is it a convention that one puts them in.

So, if they were not the default, i.e. if I would use "ISO-8859-1" how would I add them.

I like it at the top of the file and not in the middle.  I was starting 
with a doc containing the root, but I think I am changing this in which 
case I could do this append as the first thing.

Thanks for your hints and sorry if these are stupid questions or are 
answered in the specifications (frankly they are more confusing then 
helpful to me).

I am trying to figure out what tools to use (easy to use, but still 
pretty full featured) and at the same time learn XML.  I was jumping 
between lxml, elementtree and amara and just got more confused along the 
lines.  So, as elementtree will become part of Python, I assume that 
this is happening as it is the best of the crop, I will just use it.

Best regards
Werner
