The ItemID used in a Browse() call must be the value of ItemID returned with a browse element from a previous call to browse or an empty string (used to indicate a top level browse).
The ItemID is a fully qualified descriptor for the element that can be used for further browsing and as an item id if IsItem is set. Note, that it is possible for a single element to be both an item and have children (e.g. complex data items).
