Missing properties in json after unmarshalling

Hello, I came across a problem with unmarshalling process. I am attaching my xsd files and my xml file that marshalling was done upon. I am also attaching jsonschema and generated mappings. I would be grateful if you could help me, because I don't understand why unmarshalled json is (in my opinion) missing some props. XSD file that was given for jsonix to do mappings was extPL_r3.xsd.
In my xml a root element is ``````. I am having a problem with its three child props. I will start from the less deep problem.

Problem 1:
The ClinicalDocument has the `````` child tag. And the problem with this child is that in original xml it looks like this:
```<title>Skierowanie do szpitala```
And the unmarshalled equivalent in json file is:
```
"title": {
"TYPE_NAME": "referral.ST"
},
```
And marshalled version:
``````
In my opinion there should be value. I tried to pass it as string, in object etc. And nothing helped. I did find an solution by changing xsd type from "ST" to "xs:string", but I would like to avoid such an editing. Am I missing some files or something? I tried to look at referenced type of "ST" in json schema but I couldn't get a proper result.

Problem 2:
The ClinicalDocument has the `````` child tag. That tag should have a child tag: . But it does not appear in unmarshalled version.
Original xml tag looks like this:
```
...



```
Genarated json looks like this:
```
...
"code": {
"TYPE_NAME": "referral.CE",
"code": "57832-8",
"codeSystem": "2.16.840.1.113883.6.1",
"codeSystemName": "LOINC",
"displayName": "Prescription for diagnostic or specialist care Document"
},
```
There is no within.
Marshalled xml looks like this:
```

```
I think that the cause can be recursive type. But I am not sure. I tried to edit json and mapping and I didn't get proper form. Have you got any idea on that?

Thank you
