Conditions and Custom SQL in Webi SDK

I'm porting an application written using REBean in BusinessObjects 3.1 to use the new Webi RESTful SDK.  I'm currently working with BI 4.1 SP4. There are two things that I could do in easily REBean that I am having a hard time figuring out in the new SDK.

1. View condition information on a data provider -- In REBean you could use the ConditionContainer object to navigate the condition tree on a query and see all of the query's conditions, including the object name and operator.  This information doesn't seem to be included in the Data Provider Details web service so I'm not sure where to find it.  Am I missing something?  Is the Query Specification the only place where this information is available?
2. Identify whether a query is using custom SQL -- As far as I know, this is different than Freehand SQL data providers which are supported in the new SDK.  In REBean you could use SQLDataProvider.isCustomSQL() to discover if a particular query had the Custom SQL radio button selected in the universe query panel.  Again, this information doesn't seem to be included on the Data Provider Details web service.  How can I tell if a query is using Custom SQL in the new Web Services SDK?

Thanks,
