+ * 
+ * SFTP Attribute Bits for the "attrib-bits" and "attrib-bits-valid" fields
+ * of the SFTP ATTR data type.
+ * <p>
+ * Yes, these are the "attrib-bits", even though they have "_FLAGS_" in
+ * their name. Don't ask - I did not invent it.
+ * <p>
+ * "<i>These fields, taken together, reflect various attributes of the file
+ * or directory, on the server. Bits not set in 'attrib-bits-valid' MUST be
+ * ignored in the 'attrib-bits' field.  This allows both the server and the
+ * client to communicate only the bits it knows about without inadvertently
+ * twiddling bits they don't understand.</i>"
