[glue-wg] Documents for discusion in Oxford next week

[Florido Paganelli]

Hi Andrew,

Nice effort! Unfortunately I don't think I will be able to participate,
but I see there is some discussion about the enumeration types in GLUE2,
it would be nice if you or who follows can forward any outcome to me as
well.

Cheers,
Florido
