How do I represent a multi-block cylindrical system in XDMF v2?

Question

I can represent my HDF5 files using XDMF (specific type XMF used in CFD). But it is recognizing my R-Z coordinates and X-Y coordinates. It thinks I am working in 2D Cartesian X-Y. In other words, the variable X is actually Radius, R and Y is actually Z. How to correct this?

Here is the relevant snippet of XDMF:

<?xml version="1.0" ?>
