[ACTION-256]: Compile and circulate itsTool examples togehter with proposal text

Hi,
The attached file contains a revision to Yves its-tools proposal. I have 
also added revised text for mt confidence score and text analysis 
annotation revised . Finally, I have also added at the end the examples 
from these data categories, showing how the engine identification 
information (which I've now removed from the data category), can be 
repalced using the its-tools element.

There are comments that need to be addressed in the document. We can go 
through these quickly if we wish in the meeting.

cheers,
Dave
