Title: Improve string handling in xsl back calls

Sometimes XSL sends a node collection instead of a String;
this code change tries to squash the complex object into a String.

Without this code change in java, you have to perform some workarounds in the XSL code itself,
so, instead of writing
```

```
you have to transform the string with
```

```
Other use cases implies the use of more complex workaround in XSL code.
