As far as I know, yes, you can. Simply because NaN and INF and such things
are lawful member of value space. There is no reason to prohibit them, and in
fact there is no explicit statement that prohibits the use of them.

See section 4.3.7 "CoS: maxInclusive valid restriction". It is an error only
if the specified value is greater than or equal to the value of maxExclusive.

I guess it's typo. It would be better to post this to
www-xml-schema-comments@w3.org to let WG know this typo.
