Exemptions and Exceptions…?

This was raised briefly in conversation in Brussels.

Our documents and discussions use both words (Exemptions and Exceptions).  I think Aleecia has a clear idea of their difference, but I know we don't all share that clarity because I, at least, do not :-).

In my understanding, 'exemption' says that the requirements of our specification do not apply to some class of services .  An exception would be when the specification applies, but some class of services are excepted from some of the requirements.

Example from taxation:  some goods in the UK are exempt from Value Added Tax; the tax is inapplicable.  Some goods are zero-rated for Value Added Tax: they are subject to it in theory, but have an exception and are currently untaxed.


I'm not sure we have many 'exempt' classes (services that, receiving a DNT signal, can ignore it, as it doesn't apply to them).  I think we mostly have exceptions.


Aleecia, others, could you help clear my mind (and maybe others') on this?

Thanks!
