// inventory levels) in any text line of an ad (including URLs). There can
// be a maximum of two AdParameters per ad group criterion. (One with
// parameter_index = 1 and one with parameter_index = 2.)

// "{param#:value}". E.g. "{param1:$17}"

  //    and 2.000.000,10 are valid.
  //  - Can be prepended or appended with a currency symbol. For example,
  //    $99.99 and 200£ are valid.
  //  - Can be prepended or appended with a currency code. For example, 99.99USD
  //    and EUR200 are valid.
  //  - Can use '%'. For example, 1.0% and 1,0% are valid.
  //  - Can use plus or minus. For example, -10.99 and 25+ are valid.
  //  - Can use '/' between two numbers. For example 4/1 and 0.95/0.45 are
  //    valid.
