Is it possible to have an enumeration as a custom property type?

Question

I would like to have a custom property "Risk" associated to nodes. This property can only have the following values "low", "medium" and "high".

Is there a way to use an enumeration as custom property type? Of course I can use "text" but this would also allow other values for the property.

There is the option to use the type "xml", but I cannot find information or examples of its use.

No, unfortunately there is no special enumeration data type and it's also not possible to mimic such a behavior with the XML type. XML allows you to add arbitrary valid XML snippets as data.
