### Description

I found differences between PUT request body and GET response:

- .properties.format = rawxml: not returned from response
- .properties.value: expect
```


@{
var userId = context.Variables.GetValueOrDefault("UserId", "");
JObject inBody = context.Request.Body?.As();
if (inBody != null) {
inBody.Add("user_id", userId);
}
return inBody.ToString();
}

```
, but got
```


@{
var userId = context.Variables.GetValueOrDefault<string>("UserId", "");
JObject inBody = context.Request.Body?.As<JObject>();
if (inBody != null) {
inBody.Add("user_id", userId);
}
return inBody.ToString();
}

```
```json
{
"properties": {
"description": "some description",
"format": "rawxml" is not returned from response,
"value": Got "\r\n\t\r\n\t@{\r\n var userId = context.Variables.GetValueOrDefault<string>(\"UserId\", \"\");\r\n JObject inBody = context.Request.Body?.As<JObject>();\r\n if (inBody != null) {\r\n inBody.Add(\"user_id\", userId);\r\n }\r\n return inBody.ToString();\r\n }\r\n" in response, expect "\n \n @{\n var userId = context.Variables.GetValueOrDefault(\"UserId\", \"\");\n JObject inBody = context.Request.Body?.As();\n if (inBody != null) {\n inBody.Add(\"user_id\", userId);\n }\n return inBody.ToString();\n }\n\n"
}
}
```

Start by locating the Microsoft.ApiManagement/service/policyFragments@2023-03-01-preview definition in the azure-rest-api-specs repository and read the Semantic and Model Violations Reference. Compare its schema with the supplied PUT and GET traces, then determine whether the missing format property and XML transformations are specification or service behavior; done means the discrepancy and affected operation are identified with a confirmed resolution path.
