I have three possibilities. 1. Use names just as they appear in the chosen DTD. Specfically, under SVG 1.1, "text" rather than "svg:text". 2. Use a more general DTD. In this case, <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0 plus SVG 1.1//EN" would allow "svg:text" rather than "text". 3. Define another DTD to allow prefixed names as in the preceeding case. Once a DTD is specified, the document must conform to it. To my understanding, the last sentence quoted above is backwards. Also, simple and consistent terminology is preferable. "document" or "instance"; not both. I would say this. "To validate a document which uses namespaces, prefixes must appear or not, exactly as they appear in the DTD." Thanks for the help, ... Peter E. -- Telephone 1 360 450 2132.
