apim named values for xml param bicep

I am working on Azure APIM bicep deployment and most of things are working . Now I am working on parameterizing the xml policy file. How can I parameterized using name values?

I tried following two example but its not working.

E.g. I set value in xml file {{ratelimit-value}} and created named value in apim with same name. So my xml policy looks like below

<policies>
    <inbound>
        <rate-limit calls="{{ratelimit-value}}" renewal-period="60" />
        <base />
    </inbound>
    <backend>
        <base />
    </backend>
    <outbound>
        <base />
    </outbound>
    <on-error>
        <base />
    </on-error>
</policies>

When I deploy it as it I am getting error in GitHub action as below

ERROR: ***"status":"Failed","error":***"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.","details":[***"code":"Conflict","message":"***\r\n  \"status\": \"Failed\",\r\n  \"error\": ***\r\n    \"code\": \"ResourceDeploymentFailure\",\r\n    \"message\": \"The resource operation completed with terminal provisioning state 'Failed'.\",\r\n    \"details\": [\r\n      ***\r\n        \"code\": \"DeploymentFailed\",\r\n        \"message\": \"At least one resource deployment operation failed.

policy reference in bicep file

// policy for all api resources

resource apiPolicy 'Microsoft.ApiManagement/service/apis/policies@2021-08-01' = {
  name: 'policy'
  parent: api
  properties: {
    format: 'rawxml'
    value: loadTextContent('./policies/all_operations_policy.xml')
  }
}

How can I used named value created in APIm and reference in xml file dring bicep deployment
