Which tool is this? I didn't find the tool in question, so I used an 
XSLT script linked from the Relax-NG homepage. This seemed to work fine.

I had problems with this. The RNG syntax generated by DTDinst generated 
warnings when converting it back. Maybe I didn't use the latest versions 
or something.

Are you talking about specifying a fixed order of elements, vs. 
specifying arbitrary order, but each element may appear only once?

I think I agree. A fixed order is trivial to convert between the 
schematas... :-)
