- * Revision 1.4 1999/11/08 20:56:55 droddey
- * If the main xml entity does not exist, we need to get the error handling for that
- * inside the main XMLScanner::scanDocument() try block so that it gets reported
- * in the normal way. We have to add a little extra safety code because, when this
- * happens, there is no reader on the reader stack to get position ino from.

- * Swat for adding in Product name and CVS comment log variable.
