Let me question the idea of implementing resource allocation stuff in
the LaTeX kernel.  What is the appropriate way to claim resources, e.g.,
attributes, in a format agnostic pure Lua low-level module foo.lua
(which is then used in format specific wrappers/packages)?  That foo.lua
module can't certainly make use of function latex.new_attribute, since
that is only available to LaTeX users.  Or do I miss something?
