Research direction
Start with the SimpleXMLIterator::key() manual page linked in the issue and compare its documented behavior across PHP 8.0 and 8.1. Confirm the exception behavior when rewind() or valid() has not been called, then update the page so the PHP 8.1 change and the earlier false return are accurately documented.
