Cisco ASR9010 IOS-XR 5.1.x limitation on number classes per policy-map incoming policing

Hi Cisco Community,

I am currently creating a policing config for our incoming VPN customers into our data centers.

What is the current limitation on numbers of classes per policy-map for the ASR9010 with IOS-XR 5.1.0 and the following line cards and config (incoming 1R2C policing per class)?  Where would I usually find this kind of software/hardware limitation?

Thank you Sam!  Really appreciate it :)

I can see the limit is 1024 which confirms the text that I found earlier but was not sure if I understood it right: http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r5-1/qos/configuration/guide/b_qos_cg51xasr/b_qos_cg51xasr_chapter_0101.html#ID635
