In other words, why is there a where? > Because people coming from the world of SQL and other database query languages (e.g. OQL) thought that anything that calls itself a query language ought to have a WHERE clause. Apparently people who have spent years writing SQL not only find it easy to bundle together all the search conditions into one humungous boolean expression, they actually come to believe it is a good idea. Historically, remember that early proposals for XQuery (based on XQL etc) didn't build on XPath, they were developed independently. Michael Kay http://www.saxonica.com/
