text: As a complete newbie to XML this was a good starter.  As I got deeper into XML I found several mistakes/deficiencies in the book, and sometimes the author just flat out seemed to not know what he was talking about.  For instance, the claim on page 86 that (#CDATA) is a valid DTD element content definition is flat out wrong.  His description of Schema element declarations (pp. 114-115) teaches that using globals/refs is the only way to define complex elements, and is inappropriate for his example.  He makes no mention of globals at all, leaving the reader confused.  I have ceased to trust this book as a valid source of XML information
