[xquery-talk] Problem with SubFlowr-Expr

[John Snelson]

This is an operator precedence problem - you need to enclose the two 
element constructors in the return expression with parentheses and use a 
comma operator to concatenate them into a sequence:

                 return (
                     <description>{$a/description/text()}</description>,
                     <review>This is the Error</review>)
