/*!
  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
  invalid, isValid() will return \e false.

  The supported URI schemes are the same as those in the XQuery
  function \c{fn:doc}, except that queryURI can be the object of
  a variable binding.

  \a baseURI is the Base URI of the static context, as defined in the
  \l {http://www.w3.org/TR/xquery/}{XQuery language}. It is used
  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
  it is relative.

  If \a queryURI is empty or invalid, or if \a baseURI is invalid,
  the behavior of this function is undefined.
