Re: typed literals and language tags - two proposals

I see the advantage thus:

The current treatment of literals is over-complex and 
confusing.  Eliminating language tags for typed literals would be a 
considerable simplification, and as such would help to improve the take-up 
and correct implementation of RDF.
