[glue-wg] VOTE by 8/1: GLUE 2.1 for describing cloud resources?

[Salvatore Pinto]

Hi David,
I do not expect to have changes in the core abstract entities. Nor to 
the Grid Computing ones, by the way.

Cheers,
   Salvatore.

Conversely, only adding new attributes to new (cloud) entity sub-types would not require change to the base XSD (since we're just extending).  Isn't this the whole point for inheritance and sub-type specialisation?
