What I don't like is the way query languages for XML suffer because of the attributes. Attributes require a special syntax in the XML query languages, just like in XML itself. Instead of writing OQL-ish path expressions like: homes.home.id you will have to write: <homes> <home id=_ /> </homes> in XML-QL or similar languages. XQL also does not treat attributes and element equally. If you don't know whether the object you are picking is an attribute or an element, you will have to write a disjunction. There could also be a case when an element has an attribute and a subelement with the same name, you might have to guard against such case. I.e. things get messy fast. So I think if attributes are out, a lot of XML tools, including query processors will get simpler. Also there will be less opportunity for the users to screw up when using these tools.
