Hi,

I am using the XML node to convert an XML formatted string to js object. How can I convert an element value formatted as string ("true", "false") to a **boolean** datatype in the js object?  
in the [xml2js docs](https://github.com/Leonidas-from-XIV/node-xml2js/blob/master/README.md#options) there seems to be an out-of-the-box processor called **parseBooleans**

I am aware of the msg.options input in the XML node. (I use it for things like **explicitArray** )  
**valueProcessors** is another option but this needs an Array of functions as it's value.  
My question: is it possible to use this option? if so, how should I format the options message?
