Query: On the Tits cone of a Weyl groupoid   We translate the axioms of a Weyl groupoid with (not necessarily finite) root
system in terms of arrangements. The result is a correspondence between Weyl
groupoids permitting a root system and Tits arrangements satisfying an
integrality condition which we call the crystallographic property.
