Hi,

I have stuck on trying to send the clinical data as flat format for my template. I have an error in EHRBASE (could not consume Parts) with parameteres that have cardinality 0...* as last parameter, I mean:

```
clinicaldocument/recordtarget/recordtarget/recordtarget/patientrole/patient/guardian:0/organization/name:0
```

The above does not work as the "name" (as last parameter) has cardinality 0...*., or maybe my flat structure is wrong? Here you can check my template:
