Query: Pfaffian Structure with an Integrality Condition   Some Pfaffian manifolds admit the construction of an associated Weyl
line-bundle in which the lift of the Pfaffian structure defines a 2-form which
is basic. We identify the conditions under which this construction is possible,
implement it, and investigate some properties of the foliated structure of
these special manifolds and of their canonical flows.
