Roger Newson has an approach that works for any quantile, accounts for
clustering and weighting, but ignores stratification. See:
http://www.stata.com/statalist/archive/2008-12/msg00925.html
One problem with a bootstrap approach is that the weights for each
replicate must be re-normalized so that they add to the population
total.
