[vtkusers] extending VTK's XML file formats

[Bryn Lloyd]

What I meant was: you could pack your metadata into an array. This field 
data can be attached to the image. XML writers/readers will have no 
trouble reading/writing these fields. You will need to define you own 
convention how to pack your metadata into the array (e.g. each line of a 
document could be one element in the array).

All you need is a pack/unpack function.

You could also try to figure how to use vtkModelMetadata or how to write a
similar class for your needs:

> That class seems to deal with the old VTK formats. Something like that
> for the XML formats would be great.
