[vtkusers] XML question

[Reinhold Füreder]

Dear Marius,

Unfortunately I only dare to answer your probably less important
question -- in my mind it is a perfectly appropriate decision to use XML
for this task.

I have not tried to use the VTK-XML stuff directly yet, only the dataset
XML readers & writers; as you have already pointed out there will be
other XML parsers available for your task (e.g. Xerces-C++ from
apache.org), if any of the more experienced VTK gurus gives you a
negative answer.
