Re: missing bit of RDF for XML people

I had posted a similar idea here recently [1], but instead of thinking 
using blank_predicate to link the xml nodes I created blank nodes and
had the xml nodes represent relationships.

That will work a lot better than your idea because if you have more than
one country such as:


you would end up with

country  - (blank_predicate1) --> "Canada"
country  - (blank_predicate1) --> "Paris"

which would be contradiction.
