(Synchronicity -- we just covered this last week at XML One.) Range searching and queries over geospatial data are two important benefits of using an object-relational database DBMS to manage XML collections. You can do SQL queries, and even apply range constraints before inserting data. Take a look at Oracle, Informix, IBM DB2. Software AG just shipped Tamino this month. It can compose XML documents by integrating data from disparate sources, including SQL data sources. Presumably it also supports range searching. xml-dev: A list for W3C XML Developers.
