  Sets this QXmlQuery to the XQuery read from the \a queryURI.  Use
  isValid() after calling this function. If an error occurred reading
  \a queryURI, e.g., the query does not exist, cannot be read, or is

  The supported URI schemes are the same as those in the XQuery

  internally to resolve relative URIs that appear in the query, and
  for message reporting. If \a baseURI is empty, \a queryURI is used.
  Otherwise, \a baseURI is used, and it is resolved against the \l
  {QCoreApplication::applicationFilePath()} {application file path} if
