[codegen-all] XML Object schema not parsed?

Description

I implemented a couple of schemas based on XML object attributes to wrap these objects, etc.
Unfortunately only swagger-ui and handful of example generators did read and use these values, I failed to see directly working code (with or without xml serializing).

Please correct me and help if my rather exhaustive search and research was incorrect in this conclusion!!

Swagger-codegen version

Current stable and master both have this issue.

Swagger declaration file content or url

I tested multiple definitions which have same or similar xml object declarations. I verified the schema via swagger-editor and it nicely generate the examples for XML and JSON as they should have been.

For the final test, I generated random strings and set as "name" in xml nodes, used a bash script to generate for all languages and finally did a recursive search inside all files for this random string. 😋

"definitions":{
    "someModel":{
        "type":"object",
        "xml":{
            "name":"someName",
            "wrapped":true
        },
        "properties":{
            "propOne":{
                "type":"string"
            },
            "propTwo":{
                "type":"string"
            }
        }
    }
}

Command line used for generation

Tested on all languages via a bash script.
java -jar swagger-codegen-cli.jar spec.json -l -o test_outputs/

Steps to reproduce

From the looks of it, InlineModelResolver.java does not completely read the XML properties and seems to do nothing. On top of that, I failed to see any of the languages (didn't test all library combos) having these xml attributes other than server side swagger JSON or YAML files. Some of documentation and examples were generated, but didn't see any code that would do the job.

Suggest a Fix

1. Figure out or at least point us to some documentation on how to read and expose these properties
2. Update mustache files accordingly.
3. How to handle xml names, etc may depend on language, serializer, etc.

Start with InlineModelResolver.java and the language-specific mustache files; reproduce the report with the supplied schema and swagger-codegen-cli.jar command across a language. Compare generated output with the XML values shown by swagger-ui and the example generators. Done means the XML properties are either exposed in affected generated outputs or their supported limitations are documented.
