attribute 'event usage within procedure

I am using HDL Designer flow and the error I initially mentioned occurs in the "Generation step" of the ModelSim TCL flow.

With the proposed 'transaction attribute the tool passes the generation step but triggeres a compile error in ModelSim:

wait on tb_control.command'transaction;

tb_control is a record containing a signal "command"

ModelSim error:
Attribute "transaction" may not be read from formal signal parameter "tb_control".
VHDL Compiler exiting

It seems that various tools interpret these attributes differently:

1. ModelSim accepts 'event, HDL Designer doesn't

2. HDL Designer accepts 'transaction, ModelSim doesn't
