    There is one use case for XML that no system currently addresses. It is the case where someone receives a large XML, one gigabyte for example, needs to do a simple XPATH query and they need the result within a few minutes. Until recently, no software could solve this problem. Databases take too long to import the XML and XML editors could not handle large xml. My company offers a solution and perhaps you might wish to check it out. XMLMax is a simple, lightweight, indexing XML editor that can handle any size XML
    with reasonable performance for xpath queries. I think any organization that is databasing XML would have a use for XMLMax.
