title: R xml2 using XPath3.0
body: <p>I would just like to know if <code>xml2</code> R package will eventually use XPath3.0 instead of XPath1.0? I know the package is built on top of the <code>libxml2</code> C library, which still use Xpath1.0, but I can't find if there is a planned update soon to go to XPath3.0.</p>
  
  <p>Thank you!</p>
