[Getdp] Inhomogeneous Tensor[{a}, {b}, ...] parameter possible?

Dear all,

Inhomogeneous scalar material parameters can be integrated into GetDP  
as elements of a fully constrained nodal-based function space,  
following http://www.geuz.org/pipermail/getdp/2011/001407.html.

Now I would like to do the same program for anisotropic material  
parameters. I thought that some formulation like

Equation { Galerkin { [ TensorV[{a},{b},{c}]*Dof{d v} , {d v} ]; In  
Domain; Integration Int; Jacobian JVol;  }

would be possible, with a,b,c in certain constrained function spaces.

However, there comes the error "Non scalar argument(s) for function  

So, is this function manipulation with Tensor[], TensorSym[] and  
TensorDiag[] only possible with the proper functions defined on the  
specific geometric parts of the domain?

Do you know about any work-around in order to have inhomogeneous  
anisotropic parameters?

Thank you,
