In Section 2.1.5.9.29.2, Algorithm for REFS_STREAM_SNAPSHOT_OPERATION_LIST, added information about special matching characters allowed in the query.
Changed from: A search for Q is performed within the File containing S. This will match all named attributes within the file whose names match the query string Q.
Changed to: A search for Q is performed within the File containing S. This will match all named attributes within the file whose names match the query string Q.<115>
<115> Section 2.1.5.9.29.2: On Microsoft Windows the query can include asterisks to match spans of zero or more characters. No other special matching characters are supported.
