Yes - its also bounded by the "attribs.length" check. I initially thought I'd have to build an PKCS9Attributes Object consisting of 10/11+ PKCS9Attribute Objects. That didn't seem feasible since many are not supported. 

but on re-read, yes, all I need to do is stick in an OID > PKCS9_OIDS[10] - I'll update the testcase.
