This may also be a deployment issue since there are still unresolved
issues with the MS patent license.
In section 3.4.1 and Appendix A, the "/pra" scope should not be
hard-coded, this should just be specified as something like:
version = "spf2." ver-minor "/" scope *( "," scope)
With some language specifying where the first scope, "/pra" is defined,
that at least one scope must be defined by a publisher, and that if no
known scope is specified that the result is then neutral.
The problem with hard-coding this is that it requires this document to
be revisioned to replace the "/pra" scope. It's also just a nasty way
to write a specification.
