George, Perhaps overly simplified, the way to look at the 'd' attribute is that it just provides glyph geometry. The <text> element which invokes the given font (and thus a particular glyph within the font) fills and strokes the relevant glyphs using the 'fill' and 'stroke' properties on the <text> element. The 'd' attribute (after various transformations from font coordinates into the user coordinate system) provides the geometry of the shape which is filled and stroked. The transformation from font coordinates to user coordinates is a bit tricky. Unlike most of SVG where you transform coordinate systems, in the special case of the 'd' attribute, you transform coordinate values individually. This is necessary so that SVG fonts will apply stroke-width in an intuitive manner (and in a manner such that SVG fonts stroke in an equivalent manner to system fonts).
