This bug affects all levels.

The existing SVG files contained the standard staff.xml elements as non-
namespaced nodes within a SVG document.  The SVG spec says that elements in a 
foreign namespace are to be ignored.  Some implementations will ignore non-
namespaced elements, however some will reject them as unrecognized SVG 
elements.  To avoid this problem, the .svg files now place the non-SVG 
elements in an explicit namespace.  In addition, SVG specific DTD's can be 
eliminated, a rect is placed in the SVG file so viewers have something to view 
and entity references are placed in the sample files which could allow native 
SVG test running.
