26 * Encoding of the "description" argument:
28 * identifier [CODE ARG]
30 * If CODE is ':', then a lookup on table ARG is performed
31 * If CODE is '=', then a lookup in the aliased-table ARG is performed
32 * If CODE is '#', then this encodes a flag, ARG is the flag name.
34 * Aliased table for example is `CustomAttributeType' which depending on the
35 * information might refer to different tables.
