Multiple Cascade Option In SQL Server 2005

Hi All,
Use Case1:
Just wanted to know if there is something like multiple cascade delete option in SqlServer 2005.
My table structure is similar to what is given below

create table test ( id int PRIMARY KEY, tname nvarchar(55))

create table childTest ( id1 int REFERENCES test(id) on delete cascade,
id2 int REFERENCES test(id) on delete cascade, tname nvarchar(55))......

The above creation fails for childTest since both id1 and id2 reference test with ondelete cascade.

As per Books online: The series of cascading referential actions triggered by a single DELETE or UPDATE must form a tree containing no circular references. No table can appear more than once in the list of all cascading referential actions that result from the DELETE or UPDATE.

Doesn't look like a circular reference here. Wanted to confirm if it is because test is being referenced twice in the childtable.

My requirement is if a row is deleted from test, it should delete matching rows from childTest(id1 and id2). Since delete cascade is not being allowed for both columns , I have to handle the delete in id2.

Use Case2:
Also can I have INSTEAD OF DELETE and Cascade delete on the same table?
I have a cascade delete from table1 to table2. which means when any row from table1 is deleted corresponding rows from table2 are deleted. and on table2 I would like to have an instead of delete where I would like to delete rows from another table say table3.

Thanks & regards
Sunil
