[vtk-developers] xdmf questions

I am aware that others (who?) are working with xdmf and I have two 
specific questions I'd like to ask before diving in to make changes to 

1) Has anyone given any consideration to time representation withing 
xdmf. Specifically, multiple time steps and the ongoing time support in 
I need to store multiple time steps preferably in the same file, but if 
one step per hdf5 file could be referenced from the xdmf xml that's be 
ok I suppose. I don't see ant references to TIME_etc vars in the code. 
If this is in development please let me know so that I can avoid 

2) Data spaces and parallel write. I'd like to modify the xdmf writer to 
allow me to write pieces of volume data one by one  and specify the 
extents so that 8/16/64 blocks etc could be written into a single file.
Has anyone started work on this? I wuld again like to avoid duplication.

Many thanks
