MT#58441 Declare attrs in `sdp_attribute` separately

Because the attribute parts variables are declared in
one signle row, these (popping up) commentaries in other
code parts, show only the first code comment for all of the
variables, which makes the code reading confusing.

In order to fix that, declare each one separately, that
gives own code (popping up) commentary per variable.
