[Paraview] single file for AMR data: not PVD, not VTI, not PVTI,
not VTR, maybe XMF?

two questions...
though i am able to create a PVD file, which includes
differt sub-blocks of an AMR data set (as dumped from
AMROC, see http://amroc.sourceforge.net/), the number
of indivual files i include is too large for the file
system to handly happily.
so, i am trying to create one single file which contains
all the sublocks, without having to explicitly write out all
the connectivity.
the failed possibilities:
a) pvd: <Collection>... will include too many files, and there
is no way to include the data in the file pvd itself
b) vti: <Piece>...</Piece> would work, except it does
not allow for different spacing per piece (the whole
reason behind using AMR).
also cannot put several independent vti blocks in one file.
anything after the first <ImageData>...<ImageData/> gets
ignored.
c) pvti: see a) and b)!
d) vtr: works, but the connectivity has to be dumped explicitly
which inflates the size of file by at least a factor of
two, and makes it all really slow...
e) from some notes on processing Zapotec files, it seems like
the are using a single XMF and a single H5 file, and are
able to load this into paraview...

* QUESTION 1: is there a corresponding vtk/paraview format?
i would appreciate any insight!
also is there any document out there explaining what is
valid for the PVD format? is information like part, time,
and specially level being used?
<Collection>
...
<DataSet part="12" time="05680" level="3" file="amroc.hdf5.05680.043.003.vti">
...
</Collection>
* QUESTION 2: am i using level correctly?
(i did try to create internally in paraview itself a 3D "CTH AMR
Fractal", and the write out the data to examine it, but it would
crash without writing anything out...)
thanks!
(i am using version 1.9.r0 under linux)
