After you sort the namespaces, add a call to a predicate to see if the 
namespace should be output.  Make the predicate start out as
    #define nsdeclused(w, node, prefix)  (1)

Later on someone can hook in a list of non-suppressed namespace prefixes 
into the genxWriter struct, and us nsdeclused to scan the element and 
see if a given namespace prefix is visibly used (or in the non-supp list).

More importantly, make sure each element includes a parent pointer, so 
you can walk up the tree.
