That article is broadly correct, with the exception of: Unfortunately the SVG DTDs are a source of so many issues that the SVG WG has decided not to write one for the upcoming SVG 1.2 standard. The problems with DTDs are entirely unrelated to whether they are being used to describe SVG or some other grammar. There is in general a transition away from DTDs and towards W3C XML Schema (for data-like, especially database-like XML) and RelaxNG (for document-like XML) which gives greater expressive power for constraints, better typing, can do namespaces without hacks or magic prefixes, and so on. So its certainly true that for SVG 1.2 and on, startng with SVG Tiny 1.2, there is a RelaxNG schema and there is no DTD. Which means a DOCTYPE is only needed if you want to declare your own entities in the document. For SVG 1.1, the important thing is to have namespace declarations in the document; and to have a version number and baseProfile. TK> Is this the correct ways ?
