DMN17 — Chapter 11 example models contain a lot of vendor specific "noise".

The XML examples for chapter 11 contains a lot of vendor-specific noise. An example below shows a simple element with two vendor-specific additions:

```
<semantic:import namespace="http://www.trisotech.com/definitions/_5e8e877a-af87-434b-9c36-ed51c8d6b514"
name="Financial"
triso:fileId="eyJmIjp7InNrdSI6IjU1ZTFkZDA5LTdjYTUtNGUyMC04NzI1LWVlOTI5NzI2OTZkYiIsIm5hbWUiOiJGaW5hbmNpYWwifSwiciI6eyJhcGlrZXkiOiIyOTIwMDNmNjk4NDBlNzEyIn19"
triso:fileName="Chapter 11 Example/Financial"
importType="https://www.omg.org/spec/DMN/20211108/MODEL/"
drools:modelName="Financial"/>
```

The noise is distracting, makes the models overly verbose, and (IMO), the spec should not contain vendor specifics. The above need only be:

```
<semantic:import namespace="http://www.trisotech.com/definitions/_5e8e877a-af87-434b-9c36-ed51c8d6b514"
importType="https://www.omg.org/spec/DMN/20211108/MODEL/"
name="Financial" />
```

Please consider removing all vendor-specific noise from the examples.
