+\fB--stream-interface\fR \fIINTERFACE\fR
+Specify the interface to alternate data streams (ADS) in the WIM that will be
+provided by the mounted filesystem. These are a NTFS feature that found their
+way into the WIM file format.
+
+If "none", it will be impossible to read or write the ADS.

+If "xattr" (default), the ADS will be accessible through extended attributes.
+Each ADS will be an extended attribute named "user.*", where the * is the name
+of the ADS. See \fBsetfattr\fR (1) and \fBgetfattr\fR (1).
+
+If "windows", the ADS will be accessible by specifing the filename, then a
+colon, then the name of the ADS; for example, "myfile:mystream".
