K(pi,1) conjecture for the mixed elliptic motive algebra

Let $E$ be the elliptic curve and let ${\mathcal A}_{{\frak M}(E)}$ be the algebra of mixed elliptic motives equipped with its grading and differential structure. K(pi,1) conjecture. ${\mathcal A}_{{\frak M}(E)}$ is a $K(\pi,1)$ in the sense of Sullivan. The paper presents this as a stronger conjecture than cohomological connectedness, motivated by the role of minimal-model machinery in the study of the algebra and its cohomology. No resolution of this stronger conjecture is given in the supplied text.
