[rules-users] DSL and 5.3 Final

[Rob Fisher]

Having the following DSL statement coded:

[condition][]- where {VarName} is {AttributeName} and is {operator} 
{value}={VarName}: {AttributeName}  {operator}  {value}


DSLR looks like this:
ThereIsProgramHistoryData 
     - where $var01 is LevelPriorYear and is greater than 0

DSL parses to this:
ProgramHistory ($var01: levelPy  > 0) 

Parsed just fine in 5.2 Final.  Downloaded 5.3 today but am now getting
following error for every rule that uses the above DSL:

"no viable alternative at input ','"

The DRL looks like this :   ProgramHistory (  , $var01: levelPy  > 0) 

What changed in 5.3 that is causing the comma to be inserted?

Any help is much appreciated!
