> Engineering notation frequently requires a slightly modified scientific format in which the exponent is always divisible by 3.
> We should allow for an attribute (number:exponent-factor or something like) that that determines which multiples are allowed as exponents. It would be 1 for regular scientific notation, 3 for engineering notation,...
> Gnumeric currently only allows regular scientific notation and engineering notation and uses a foreign attribute  "gnm:engineering"  to <number:scientific-number>. A value of "true" indicates that the exponent will always be a multiple of 3.
> In this proposal I intend to provide for a more general situation by providing an attribute to <number:scientific-number> that has, at this time, the two integer values 1 and 3 as possible values. This will permit easier extension if any implementation desires to allow other multipliers.
