Restrict File creation types

[Kenny <selinux@kfk2.com>]

How would I go about restricting all files created in a certain
directory to a set of types. Eg:
I have Dir Types:
Dir_Type1_t
Dir_Type2_t
and file Types:
File_type_1a_t
File_type_1b_t
File_type_2a_t
File_type_2b_t

I want all files in Dir_Type1_t to be of types File_type_1a_t or
File_type_1b_t no matter the domain of the creating process 
and all files in Dir_Type2_t to be of types File_type_2a_t or
File_type_2b_t.
(mkdir -Z user:object_r:File_type_2a_t TEST in a dir of type
Dir_Type2_t should fail as any user/role/domain)

I've tried looking through the logs with auditallow on for all the Dir
and File types, but didn't see anything where both types where listed
in the same allow statement.  Is this even possible?
