[occi-wg] Enumerations for attributes

[Gary Mazz]

Hi,

I know we said we were going to defer this topic, ... but the actions 
now have a attribute called "method" method has  enumerated values 
associated with them.. We need a way to define these values/options.

We could use the  brace []  since the curly braces are in use for 
delimiting attribute properties.

 > POST /compute/?action=stop HTTP/1.1
 > [...]
 > Category: stop; scheme="[...]"; class="action";
 > X-OCCI-Attribute: method=poweroff["graceful", "acpioff", "poweroff"]

With method undefined
 > POST /compute/?action=stop HTTP/1.1
 > [...]
 > Category: stop; scheme="[...]"; class="action";
 > X-OCCI-Attribute: method=["graceful", "acpioff", "poweroff"]

cheers
