Quoting Bjoern Hoehrmann <derhoermi@...240...>:

If you refer to the use of the SVG Namespace, the latest specification uses urn:oasis:names:tc:opendocument:xmlns:svg-compatible:1.0 for SVG elements and attributes (and similar ones for SMIL, XSL-FO, etc.)

Excellent news! Sounds like the SVG WG got them straightened out after all.
