Description Michael Kay 2013-05-06 14:46:07 UTC 
In the syntax summary we show xsl:accumulator/@initial-value as optional, but the prose doesn't say what happens if it is omitted. We could say that the default is an empty sequence - provided that is consistent with the @as attribute - or we could say that it is mandatory. I think my preference is for making it mandatory.
Comment 1 Michael Kay 2013-05-23 16:52:41 UTC 
Agreed to make this attribute mandatory.
Comment 2 Michael Kay 2013-05-23 17:01:42 UTC 
Change has been applied.
