I don't think you should have a rule of thumb for maximum size for data, be it XML or anything else. If you need to store multiple gigabytes of data, then you store that data. What makes a difference is what API you use to process that data. However, XML may not be your best bet if your data set is very large. In those cases a relational or XML database will probably work better than a single XML file.
