Blanks between () causes syntax error in DSL expansion

// === DSL ============================================
[keyword][]greater than=>
[condition][]- where

{VarName} is {AttributeName} and is {operator} {value}=
{VarName}

:

{operator}

// === DSLR ===========================================
rule lpygt0
when
ThereIsProgramHistoryData

• where $var01 is levelPriorYear and is greater than 0
  then

  // ====================================================

produces incorred DRL due to the redundant spaces in ProgramHistory ( )

ProgramHistory ( , $var01: levelPriorYear > 0 )
