Great!

I'm having lots of real-life distraction ATM, so my feedback will be coming in 
a piecemeal fashion:

Generated code looks correct to me. However,
a) An example for using case and default would be really helpful.
b) Perhaps the function signature could be simplified to

rk.XML.switch(condition, modifier = NULL, cases, id.name = "auto")

# if there are exactly two cases, and their standards are logical(!) 
TRUE/FALSE, generate a true/false switch
rk.XML.switch ("foo", cases = list (
    list (standard=TRUE, fixed_value="foo"),
    list (standard=FALSE, fixed_value="bar")
))

# otherwise a "case" switch. If the final case specification has no standard 
(or standard=NULL), make it a <default>.
rk.XML.switch ("foo", cases = list (
    list (standard="square", fixed_value="foo"),
    list (standard="circle", fixed_value="bar"),
    list (fixed_value="other")
))

(If it wasn't for the optional "modifier" argument, cases could even be passed 
through a "..." argument, which would remove the need for a nested list).
