Re: rdfa parsing problem

Thanks a lot Philip. And thanks for the pointer, it may help in future 
if similar circumstances arise.

The bad news (for me:-) is that the change the parser does on the DOM 
tree does not really explain the outcome of Meri's test, so there might 
be a bug in the rdfa distiller:-( I will have to check.

Thanks again

Ivan
