## Microsoft.ApiManagement/service/policyFragments@2022-04-01-preview - ROUNDTRIP_INCONSISTENT_PROPERTY

### Description

I found differences between PUT request body and GET response:

- .properties.value: expect
```


@{
return ((666 & 0xFF) << 8).ToString();
}

```
, but got
```

@{
return ((666 & 0xFF) << 8).ToString();
}

```
```json
{
"properties": {
"description": "Test policy fragment",
"format": "rawxml",
"value": Got "\r\n\t\r\n\t\t@{\r\n\t\t\treturn ((666 & 0xFF) << 8).ToString();\r\n\t\t}\r\n\t\r\n" in response, expect "\n\t\n\t\t@{\n\t\t\treturn ((666 & 0xFF) << 8).ToString();\n\t\t}\n\t\n\n"
}
}

Start with documentation/Semantic-and-Model-Violations-Reference.md and locate the Microsoft.ApiManagement/service/policyFragments 2022-04-01-preview specification. Compare the reported PUT value with the GET response and determine the specification change needed; done means the round-trip no longer produces the reported inconsistency.
