Description Michael Kay 2016-10-31 17:24:07 UTC 
In 2.8.3.1, the signature of the accessor function

dm:array-size($array as array()) as xs:unsignedLong

could be read as implying that implementations must allow an array with 2^64-1 members, or alternatively that they must not allow it to have more than this number. I don't believe either of these interpretations is intended.

I suggest therefore that the type of the result be changed to xs:nonNegativeInteger.
Comment 1 Andrew Coleman 2016-11-04 14:12:38 UTC 
The WG agreed.  The change has been applied.
