I would definitely leave it to other grammars like XQL to do any complex structural searches. (On a quick skim of the proposal, it looks to me as if some changes would be needed to apply XQL to a search over the structured properties of a collection of resources, as opposed to a search within the content of a single resource.) But I do think it would dramatically increase the usefulness of basicsearch at not much cost to add something along the lines of Alan's proposal. Really all that's needed is something along the lines of his proppath element, and changing the definitions of the comparison operators and the isdefined operator to let them take a proppath as their first argument. --Judy Judith A.

The XQL query language can do structured queries on XML.

Any hierarchical structure may present itself as XML, even if it is not physically stored as such. So a document hierarchy in a proprietary format can still look like XML to the query language. Hope this is helpful. Jonathan jonathan@texcel.no Texcel Research http://www.texcel.no
