\setupbackend[export=yes]
\setupexport[properties=yes]

\starttext
      \startelement[test][this=that]whatever\stopelement
\stoptext

arbitrary empty elements are tricky as there is no content then, so that 
needs thinking

(you can of course abuse \startelement

\startelement[br]x\stopelement

and then remove the x from the exported xml. I'll think about it (no 
time now).
