Hi This expression: replace("aaaa bbbbbbbb ddd ",'(.{6,15}) ','$1@') results in [FORX0002] Invalid pattern: 'Illegal quantifier, lower > upper bound: {6,1}'.
Could it be that *S*{n,m} is only accepting single digit n and m?
This causes http://stackoverflow.com/questions/3767452/xquery-word-wrap to wildly overwrap.
