IRM Web Services Adding a New Role to a Context

Question

We are in the process of using the IRM web services to create a system that will automatically create users/contexts and seal documents over the web.
So far I can successfully create users and groups and assign permissions properly as well as create context.
I am having trouble adding roles to the context.
The error I'm getting is "The attribute 'Features' is mandatory".
The problem is that there is no function to add features to the ContextRole object.
How do I set up the features so that I can save then new ContextRole?

Hi Tom
Response from engineering on your latest questions:
Depending on which web service code generator is used, collection typed properties may or may not be provided with set operation. If the code generator does provide a set method for collections, then you can just specify the set of features you require as so:
// Java
Collection<Feature> features = new ArrayList<Feature>();
features.add(feature);
ContextRole role = new ContextRole();
role.setFeatures(features);
However if the set method is NOT provided, then you need to manipulate the collection directly, by using the get method and then using the standard collection methods to alter the contents.
// Java
ContextRole role = new ContextRole();
role.getFeatures().add(feature);
These two examples are functionally the same, they both create a context role object with one feature.
Kind regards
