Well, sure! But if you want a useful answer you've got to ask a specific question with reference to actual code and actual XML. Otherwise the answer is always the entire language. Understanding the whole comes from understanding an accumulation of parts and understanding the individual parts comes from making specific mistakes. An unwillingness to make mistakes in public is a hindrance to learning. -- Graydon Saunders | graydon...@gmail.com Þæs oferéode, ðisses swá mæg. -- Deor ("That passed, so may this.")
