No, there are a few others, for example using qnames without a matching PREFIX, FILTERing on variables that aren't mentioned and so on. There's also things like projecting * when there's no variables, or projecting unmentioned variables. I'm not sure if they're technically errors, but it still pays to look out for them to issue a warning or something. - Steve -- Steve Harris, CTO, Garlik Limited 2 Sheen Road, Richmond, TW9 1AE, UK +44(0)20 8973 2465 http://www.garlik.com/ Registered in England and Wales 535 7233 VAT # 849 0517 11 Registered office: Thames House, Portsmouth Road, Esher, Surrey, KT10 9AD
