Pseudo-units
It is possible to use the keywords "depth", "height", and "width" as a pseudo-unit for the attributes depth, height, lspace, voffset, and width. They represent each length of the same-named dimension.
 Prior to Gecko 7.0 (Firefox 7.0 / Thunderbird 7.0 / SeaMonkey 2.4) the MathML2 pseudo-unit lspace was allowed, which is no longer present in the MathML3 Recommendation and has been removed now.
