It does that via entity declarations in the internal DTD subset. I assume that your file still has these. If you are using a DTD for validation, since DTDs are not namespace aware you will need to declare the namespace declarations (DTDs consider these to be attributes); either in the internal DTD subset or in your local copy of the SVG DTD. -- Chris Lilley Technical Director, Interaction Domain W3C Graphics Activity Lead, Fonts Activity Lead Co-Chair, W3C Hypertext CG Member, CSS, WebFonts, SVG Working Groups
