Query: A building-theoretic approach to relative Tamagawa numbers of
  quasi-split semisimple groups over global function fields   Let G be a semisimple quasi-split group defined over a global function field.
We express the relative Tamagawa number of G in terms of local data including
the number of types of special vertices in one orbit of the Bruhat-Tits
building over some completion with respect to a place and the class number of G
at that place.
