Does the "This" refer to our proposed repair mechanism for adding  
time zones to dateTimes without timezones?
I thought being a bit more explicit by having an example would be  
helpful for them.

Is the proposal for treating them as intervals coming from the XML  
Schema spec? If so, it's probably worth pointing out what where and  
giving an explicit example.

Are we asking for a justification or are we saying we would prefer to  
use -12 to +14?

Had trouble resolving "This". The previous paragraph is about  
xsd:decimal and I didn't understand the connection.

Should this be included in this communication or be in a separate  
one? If it is separate and included in this communication consider  
having the subject line mention it.
