[glue-wg] comments about cloud attributes in GLUE2.1 draft

[Baptiste Grenier]

Hi Stephen,
For the In/Out ports we could use the NetworkConfigurationPort_t t6ype
instead of UInt32, it would allow '80', '80,443' and '2000:25000'. Would it
be OK?

For the IntanceMax/Min attributes: it's useful for us to be able to
know the capacity and the specificities of the infrastructure.

Cheers,
Baptiste
