Its just a bit confusing, because everywhere (eg. DataItem) else the
keyword "Dimensions" expects first x,y,z and not z,y,x
I think "Dimensions" should behave always the same.
Greetings

see this part of my xdmf-file:

<DataStructure
Name="Origin" DataType="Float"
Dimensions="3" Format="XML">

</DataStructure>
<DataStructure
