Description Michael Kay 2014-03-17 18:16:23 UTC 
Tes cbcl-avg-010 is:

avg((xs:double("NaN"), current-date() - xs:date("1997-01-01") ))

I believe that under "Errors and Optimization", NaN is a legitimate result. Once an xs:double NaN value has been found in the input sequence, the only possible outcomes are NaN or an error, so the processor is entitled to take an early bath and return NaN.
Comment 1 Tim Mills 2014-09-24 11:04:54 UTC 
Agreed.
Comment 2 Michael Kay 2015-01-03 17:22:31 UTC 
Fixed as suggested.
