the input parameter 'ignoreCase' is documented as being DataType "boolean" but if you use boolean, you get an error similar to
_"Message": "Execution of ClaimsTransformationImpl of Type \"Microsoft.Cpim.Data.Transformations.EqualityTransformation\" for TransformationMethod \"CompareClaimToValue\" of ClaimsTransformation with id \"xxxxxxx\" in policy \"B2C_1A_P1_V1_SuSiUAT\" of tenant \"xxxxxxxx.onmicrosoft.com\" threw an exception with the following message: Unable to cast object of type 'System.Boolean' to type 'System.String'.",
in unit-tests/claims-transformation/string/CT_CompareClaimToValue.xml
the CT "CheckStrings-Equal" doesn't conform to the documentation..

So the code sample is correct, but the docs are incorrect on this point..
