Utility of "semantic" parameter in formSerialize
I may have missed it but there does not appear to be anything in the HTTP specification about the order of elements in form submissions. Server code cannot assume anything about ordering, if that's true.
The "semantic" parameter to formSerialize in the form plug-in claims it will order fields using the same order as the browser. What that has to do with semantics escapes me, but what purpose does it serve?
