\startluacode
     function xml.functions.processJSON(t)
         buffers.assign("foo","\\startJSON\n" .. tostring(xml.text(t)) 
.. "\n\\stopJSON")
         context.getbuffer { "foo" }
     end
\stopluacode

\startxmlsetups xml:json
     \pushcatcodetable
     \setcatcodetable\ctxcatcodes
     \xmlfunction{#1}{processJSON}
     \popcatcodetable
\stopxmlsetups

(If needed I can make a better plugin for this ... remind me later this 
year.)
