Ugh, I should avoid opening your emails while eating supper.

According to the schema

<xs:attribute name="value" type="xs:double" use="optional"/>

NaN is not a double. I thought that according to the IEEE standard, NaN 
values have the property that comparing them with a double should always 
be false. So value="Nan" strikes me as an Oxymoron and we should not 
allowed.
