See http://www.croczilla.com/~alex/conformance_suite/svg/coords-units-02-b.svg. We're failing on the percentage units tests.
FIXED? That URL is the same test as: http://www.croczilla.com/~alex/fosdem2003/w3c-conformance-suite/coords-unitsProc-BE-04-ps.html It looks bad linking directly to the svg because it should be constrained to a 480x360 (or same ratio) viewport.
I think the latter test is an old version. I don't find the specs particularly clear on this, but I'm pretty sure percentages should be based on the viewport element's user coordinate system, not the viewport itself. See also this example: http://www.croczilla.com/~alex/reference/SVG/REC-SVG11-20030114/images/coords/Units.svg and the reference image: http://www.croczilla.com/~alex/reference/SVG/REC-SVG11-20030114/images/coords/Units.png We fail the percentage tests in the right column. (We also fail the em-unit tests in the middle column, but that's a separate issue). The spec say about this test: (http://www.croczilla.com/~alex/reference/SVG/REC-SVG11-20030114/coords.html) The three rectangles on the right demonstrate the use of percentages. Note that the width and height of the viewport in the user coordinate system for the viewport element (in this case, the outermost 'svg' element) are 4000 and 2000, respectively, because processing the viewBox attribute results in a transformed user coordinate system. The topmost rectangle, which is specified in percentage units, is exactly the same size as the middle rectangle, which is specified in equivalent user units. In particular, note that the 'stroke-width' property in the middle rectangle is set to 1% of the sqrt((actual-width)**2 + (actual-height)**2)) / sqrt(2), which in this case is .01*sqrt(4000*4000+2000*2000)/sqrt(2), or 31.62. The bottom rectangle of the group illustrates what happens when values specified in percentage units are scaled.
Actually the specs are quite clear: http://www.croczilla.com/~alex/reference/SVG/REC-SVG11-20030114/coords.html#Units: For percentage values that are defined to be relative to the size of viewport: * For any x-coordinate value or width value expressed as a percentage of the viewport, the value to use is the specified percentage of the actual-width in user units for the nearest containing viewport, where actual-width is the width dimension of the viewport element WITHIN THE USER COORDINATE SYSTEM for the viewport element.
