Expr Language - Conditional Expressions

Simple "IF" expressions can be declared using the IF() function, but for more elaborate IF cases, with multiple conditions and/or requiring an ELSE option, a conditional expression can be used.

WITH total = x + y:
  IF total > 0:
     x / total
  ELSE : error

Note: the ":" after "ELSE" is optional – in the example above, we've included it for readability.
