  We consider renormalization effects for a bosonic QCD-like string, whose
partons have $1/p^{2}$ propagators instead of Gaussian. Classically this model
resembles (the bosonic part of) the projective light-cone (zero-radius) limit
of a string on an AdS${}_5$ background, where Schwinger parameters give rise to
the fifth dimension. Quantum effects generate dynamics for this dimension,
producing an AdS${}_5$ background with a running radius. The projective
light-cone is the high-energy limit: Holography is enforced dynamically.
