SYSTEM/SIMULATION/MODELSIM woes

I am writing a class.ptf file that has a MODULE_DEFAULTS/SIMULATION/MODELSIM section as follows:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

MODELSIM

{

TYPES

{

}

SETUP_COMMANDS

{

ops = "virtual type {OR AND XOR NOT MOV ADD SUB CMP LSLI LSRI ASRI ROTI MOVI ADDI SUBI CMPI LD {5&#39;b10100 ST} {5&#39;b11000 BR} BSR RET {5&#39;b11111 IFS} {default ILL}} Opcode";

conds = "virtual type {nc c nz z pl mi lt ge gt le nv v hi la {default ill}} Condition";

opc = "virtual function {(Opcode) (__MODULE_PATH__/next_instruction[4:0])} opcode";

}

}[/b]

--- Quote End ---

and this gets transferred over to the system ptf file as you would expect, but when I generate the project in SOPC Builder, I get a rather lengthy set of errors, starting with

<div class='quotetop'>QUOTE </div>

Now apart from the fact that the error messages are even less readable than the PTF format itself, I have no idea what&#39;s wrong, even after looking at the few Nios PTF&#39;s for old boards that contain MODELSIM sections.

Before anyone suggests this, getting rid of the {n NAME} bits from the virtual type command and having a pure {NAME NAME NAME} command doesn&#39;t make any significant difference, and anyway I suspect it is not the command itself that is getting complained at.

Many thanks for anyone who can help.
