The following array initialization worked fine in VHDL-2002:
type PACKET_REG_TYPE is array (0 to PACKET_LEN_MAX - 1) of std_logic_vector(7 downto 0); -- Packet array definition: (PACKET_LEN_MAX) deep x 8-bit wide.

signal tx_byte_sr : PACKET_REG_TYPE;

tx_byte_sr <= (others => (others => '0'));

Now, with VHDL-2008, it gives: (vcom-1320) Type of expression "(OTHERS => '0')" is ambiguous; using element type STD_LOGIC_VECTOR, not aggregate type PACKET_REG_TYPE.

I can't find any documentation on the "new" way to initialize arrays in VHDL-2008.
