Cortex series scheme NEON has rename SIMD register?

Note: This was originally posted on 18th April 2013 at http://forums.arm.com

NEON contains 16 SIMD user visible registers q0~q15, while does it have more architecturally visible register? Just like general 32 bit register engaged.
Anybody know which document or spec demonstrate related topic?
Thanks to any interesting discussion!
