After consulting with Rob Richie of FairVote---an NGO here in the US
that champions, in part, forms of alternative voting---the U.S. only
uses a few types of counting methods, notably:

* plurality voting (a/k/a "first past the post")
* cumulative voting (where each voter can allocate a fixed number of
votes to a slate of candidates)
* limited voting (a multi-candidate plurality election where voters
have fewer votes than the number of candidates that can be elected)
* instant-runoff voting (single-winner ranked-choice voting)

There are many variations of the above; for example, some plurality
elections require a certain threshold to be met before a
candidate/issue can win or they require a partisan or non-partisan
runoff (usually if no one wins a majority after the first election).

FairVote keeps a slightly out-of-date (leaves out Port Chester, NY use
of cumulative voting) list here:

David, in terms of your schema-ese, the only one that seems to be
missing from my bullet list above is limited voting.  Of course, I'm
not sure what most of the three-letter abbreviations are without some
xs:annotation elements in there (despite having worked at NASA, my
backronym-ing abilities are just slightly enhanced). ::)

best, Joe
