I was recently bitten by this too, and I consider it a bug in the manpage.

       -d, --dump
           Dump  the  values  of all extended attributes associated with path‐

I'd say it's not unreasondable to read this and think that -d dumps *all*
extended attributes, because that's what it says.

Only if you read later do you find:

       -m pattern, --match=pattern
           Only include attributes with names matching the regular expression
           pattern.   The  default  value  for  pattern  is  "^user\\." ...
