XML Signature 1.1 changes explanation

I have created a document noting the changes in XML Signature 1.1 from  
the Second Edition.

This is for the First Public Working Draft:

Please review and note any corrections.

This does not reflect changes since FPWD, though I expect we can  
update the following for that (currently the same content)
