Recently, an editor asked me to clarify a number of questions she had about XML. She had been taking scrupulous notes during a number of meetings and presented me with a long list of conflicting information. She was baffled, frustrated, and didn't know what to do.
Her confusion was completely understandable, as there is a lot of information (and misinformation) about XML. Those of us who specialize in markup languages have an interest in maintaining that confusion because we profit from it. No doubt
