** Description **

[SC]: I've just been reading about Genx [http://www.tbray.org/ongoing/genx/docs/Guide.html] which is 
a C library for generating XML written by Tim Bray. The main differences between the 
capabilities of xmlgen and Genx seem to be:

   * Handling of XML Namespaces
   * Generation of Canonical XML [http://www.w3.org/TR/xml-c14n]

So, I had a quick think about how to do namespaces with xmlgen and came  up with the following
syntax: 

 xmlns rdf "http://http://www.w3.org/1999/02/22-rdf-syntax-ns\#"
 xmlns rdfs "http://www.w3.org/2000/01/rdf-schema\#"

 declaretag foo -namespace rdf
 declaretag bar -namespace rdfs

 foo ! {
     bar - This is content
     bar - this is also content
 }

To make this work, the root element should have the namespace declaration
attributes included:

 <foo xmlns:rdf="http..." xmlns:rdfs="http...">
   <bar>...</bar>
 </foo>

A quick look at the code makes me think that this modification might not
be too hard to make (add the ns attributes in makeTagAndBody when 
the indent is "" -- or perhaps more properly add a nesting 
counter and add the attributes when it's zero).   Having figured 
this out I might well go an implement this next time I need to 
generate XML with namespaces, this note is just in case anyone
else wants to have a go instead.
