The intrinsic width and height of the viewport of SVG content must be determined from the width and height attributes. *If these are not specified, the default values of 100% must be used.* The intrinsic aspect ratio of the viewport of SVG content is necessary for example, when including SVG from an object tag in XHTML styled with CSS. The intrinsic aspect ratio must be calculated based upon the following rules: * If the width and height of the root SVG element are both specified in absolute units (in, mm, cm, pt, pc, px) then the aspect ratio is calculated from the width and height after resolving both values to the same units. * If either/both of the width and height of the root svg are in percentage units, the aspect ratio is calculated from the width and height of the viewBox. If the viewBox is not present, or set to 'none', the intrinsic aspect ratio cannot be calculated and is unspecified. Regards, Craig Northway
