But then Danny wouldn't be in the running for the "most surprising use of an XQuery library" award.... I understand the winner for this year will be announced in Amsterdam? Danny, when looking at the parse tree be sure to check for the 'external' token. If the variable name and optional type declaration aren't followed by 'external', then the variable can't be set externally. In 5.0-3.3 it looks like such attempts are ignored. xdmp:eval(' declare variable $assetId := "x"; $assetId', (xs:QName('assetId'), 'fubar')) => x xdmp:eval(' declare variable $assetId external; $assetId', (xs:QName('assetId'), 'fubar')) => fubar -- Mike On 5 Sep 2012, at 11:10 , John Snelson wrote: > I'm not sure xqysp will do what you need.
