I want to make a large addition to the spelling rules and the postags. Although I can partly automate the task, there's a lot of work, which will be wasted if there are objections after I do the work. Thus, I ask for your comments now.
For spelling, LT correctly ignores only a very small number of SI units of measurement when they are combined with a prefix or a suffix such as 'mega', 'pico' and so on (www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf). For example, I get spelling errors for these words: picoliter, femtoliter, megameters femtometers, and picosievert. Also, these words do not have postags.
LT ignores adjectives such as '10-megohm', '5-microgramme', and '7-centimetre' (section 5.3.3 in www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf). But, for gramme/gram, litre/litre, metre/meter, the LT spelling rules do not find terms that are used incorrectly such as 10-litre in American English.
I want to these things:
* Add postags for all the SI units of measurement.
* Add locale-specific spelling for Ame and BrE
Can you think of any reasons not to do these things?
