  Let p be a prime. We study pro-p groups of p-absolute Galois type, as defined
by Lam-Liu-Sharifi-Wake-Wang. We prove that the pro-p completion of the
right-angled Artin group associated to a chordal simplicial graph is of
p-absolute Galois type, and moreover it satisfies a strong version of the
Massey vanishing property. Also, we prove that Demushkin groups are of
p-absolute Galois type, and that the free pro-p product -- and, under certain
conditions, the direct product -- of two pro-p groups of p-absolute Galois type
satisfying the Massey vanishing property is again a pro-p group of p-absolute
Galois type satisfying the Massey vanishing property. Consequently, there is a
plethora of pro-p groups of p-absolute Galois type satisfying the Massey
vanishing property that do not occur as absolute Galois groups.
