Doesn't look like that: rjsx-parse-xml seems like a routine to parse and 
return an xml parse node.

Seems like it's the command called 'rjsx-electric-gt' defined here: 
https://github.com/felipeochoa/rjsx-mode/blob/b697fe4d92cc84fa99a7bcb476f815935ea0d919/rjsx-mode.el#L916

js2-DIV is defined in js2-mode.el (which is a dependency). The value is 
a number which denoted the node type. But might be unnecessary, given 
the above.
