Lyor Goldstein commented on SSHD-1226:
--------------------------------------

As far as I can tell the client side code supports attributes extensions 
seamlessly - see {{SftpClient#Attributes.getExtensions()}}. On the server side 
we need to add some user hooks (which may take some time). If you don't want to 
wait, you can derive your own {{SftpSubsystem}} and override:
{code:java}
protected NavigableMap<String, Object> getAttributes(Path path, int flags, 
LinkOption... options)
            throws IOException {
    NavigableMap<String, Object> attrs = super.getAttributes(path, flag, 
options);
    Map<String, Object> extra = (Map<String, Object>) attrs.get("extended");
    if (extra == null) {
       extra = new HashMap/TreeMap<>();
       attrs,put("extended", extra);
    }
    
    ... add custom attributes - either extra.put(String, String) or 
extra,put(String, byte[])...
    return attrs;
}
{code}
