I agree with Phil, that the additional dimensions should be moved out of the range of mathematical font dimensions, in order to avoid unpleasant misinterpretations of them. The set Michael Downes proposes looks very good, for european usage there probably should be values for accented capital and lowercase letters added. font_baselineskip is, though projected, not actually assigned a value yet (I just looked it up!). As it is projected, the assigned value can be everything the font designer want to give it, it is not easily calculated from some other known dimension. Of course, at last all font dimensions are calculated somehow from the design size (a combination of table lookup and interpolation). How much does superfluous font dimensions cost (in terms of TeX internals and processing speed)? Are there known data? Unfortunately, I don't have easy access to ISO/IEC 9541-1:1991(E) (font standard) which Michael Downes mentioned, what is the essence of this standard? As far as I know, fontinst tries its best to assign the additional font dimensions to the T1 encoded fonts, but I don't know how it achieves this. --J"org Knappen
