/**
* A finite element, which is the trace of FE_Q elements, that is a tensor
* product of polynomials on the faces, undefined in the interior of the cells
- * and continuous. The basis functions on the faces are from
- * Polynomials::LagrangeEquidistant
+ * and continuous. The basis functions on the faces are formed by a tensor
+ * product of 1D Lagrange polynomials with equidistant points up to degree 2
+ * and Gauss-Lobatto points starting from degree 3.
*
* This finite element is the trace space of FE_Q on the faces.
*
* polynomial. In order to make the use of FESystem simpler, FEValues objects
* will not fail using this finite element space, but all shape function
* values extracted will equal to zero.
- *
- * @todo Polynomials::LagrangeEquidistant should be and will be replaced by
- * Polynomials::LagrangeGaussLobatto as soon as such a polynomial set exists.
