I think there is something missing in fuction xmlDumElementContent in
module valid.c (modified lines follow)

static void
xmlDumpElementContent(xmlBufferPtr buf, xmlElementContentPtr content,
int glob) {
  if (content == NULL) return;

  if (glob ||  content->ocur > 1 && content->type>2)  /* code added
after || */
    xmlBufferWriteChar(buf, "(");

   ..... unchanged code here


 if (glob || content->ocur > 1 && content->type>2) /* code added after
|| */
        xmlBufferWriteChar(buf, ")");

  ... unchanged code follows

} 

The reason: a model group like ( x, (y, z)*)
needs a parenthesis grouping (y,z) even if this is a sequence inside a
sequence.
However when dumped I got (x, y, z*)
