XML Fragment Property Populated from SQL Query

I'm investigating using Opencities Map to connect to various business properties utilising the DB Property value.... these would all be read only and "live linked via an sql query..."

I'm having trouble finding documentation on how to accomplish this.
I can't get the xml fragment to be populated with the DB property.... 

The XML for a feature definition below seems to be populating both NestedBusinessProp and BusinnessStringProp directly onto the Feature....

I'd expect it to have the following.....

<MyBusinessPropertyFeature>
  <ObjectId/>
  <BP>
    <NestedBusinessProp />
  </BP>
  <BusinnessStringProp/>
</MyBusinessPropertyFeature>

However it ends up
<MyBusinessPropertyFeature>
  <ObjectId/>
  <BP/>
  <NestedBusinessProp />
  <BusinnessStringProp/>
</MyBusinessPropertyFeature>

I currently get around all this geospatial admin project setup by importing the data, I'd rather use in-built function.

Hopefully this will expose the properties to be used in theming and reports....
