There is indeed a tradeoff to find between encoding things in "complex"
literals and making them explicit in resources.

Note that checking the consistency of measurements as blank nodes
requires ad-hoc implementation as well : it is not possible to state
that any resource with :grams "1000" must have :kg "1"... An the problem
of rouding remains...
