Which version of VHDL sup****ts delimited comments.

Hi,
I am new to VHDL. The book "The designer's guide to VHDL", 3rd ed.
says:

VHDL-87, -93 and -2002
These versions of VHDL only allow single-line comments, not delimited
comments.

I am very curious which version VHDL allows delimited comments.


Thanks a lot.
