vlakoff has just submitted a new pull request for https://github.com/w3c/svgwg: == Clarify that SVG requires well-formed XML, not valid XML == Addresses #960. cc @real-or-random ## Changes ### Drop "valid and" from the Document Conformance Classes intro The intro sentence currently reads: > Additional conformance classes depend on whether the content is also valid and well-formed XML. None of the conformance classes defined in this section require XML *validity* in the XML 1.0 sense — that is, conformance to a DTD. Only *well-formedness* is required. Removing "valid and" brings the intro into agreement with the conformance classes that follow it. ### Add a clarifying note Adds a note immediately after the intro paragraph making two things explicit: - SVG 2 defines no DTD, and user agents do not perform DTD-based validation. - A `<!DOCTYPE>` declaration and an XML declaration (`<?xml …?>`) are neither required nor recommended for SVG documents served as `image/svg+xml`. Without this note, a reader could reasonably infer from the surrounding XML-related language that some form of XML validity is expected. The note removes that ambiguity without touching any normative text beyond the one-word fix above. ## Tests No web-platform-tests PR is needed. This is a purely editorial change: no normative requirements are added or removed.
