Class attribute

[Alexandre Chapellon]

Hello,

This message is more precisely direted to Alan.
I have noticed that the "Class" attribute as defined in rfc2865 is a
string value, but looking at dictionary that comes with freeradius i saw
that it's an octet value.
As far as I know none of the rfc updating 2865 redefine the class attribute.
Is there a reason for this, is it safe to make it a string value?
