Amazon Mechanical Turks Qualification Multiple Locals

I am trying to define a worker qualification for a HIT via command line tool.

The requirements to workers are

• Locale: US, CA

• Number of accomplished HITs >= 30

• Acceptance rate >= 75%

The following is the part of external_hit.properties file

# Worker_PercentAssignmentsApproved > 75%
qualification.1:000000000000000000L0
qualification.comparator.1:greaterthan
qualification.value.1:75
qualification.private.1:false

# Worker_Locale
qualification.2:00000000000000000071
qualification.comparator.2:in
qualification.LocaleValue.2.Country.1=US
qualification.LocaleValue.2.Country.2=CA

# Worker_NumberHITsApproved > 30
qualification.3:00000000000000000040
qualification.comparator.3:GreaterThan
qualification.value.3:30

The problem is I am not sure about the syntax, especially about this part, I made up this part.

qualification.LocaleValue.2.Country.1=US
qualification.LocaleValue.2.Country.2=CA

I didn't find any example in command line tool format with multiple locales.

I appreciate if you could check the syntax.
