Scope for extended attribute list of values


When defining an extended composition on an existing class, is it the active instance of that class visible to template code in the extended sub-object (eg for generating a list of values), and if so, how do you access it? In script generation, you can use ActiveSelection, but this does not seem to be available in the context of a form.

The specific problem I am trying to solve is adding support for filtered indexes to the SQL 2012 DBMS. The simple approach would be to add a free-text attriute for the filter condition, but I would prefer to have the columns referenced in the condition linked to the table column definition. This means creating an extended sub-object with an attribute whose list of possible values is the column collection for the associated table. Is this possible?
