Hi there, I am currently implementing PuSH for Google hub.
I am having an issue with current definition of verify token in parag 6.1. hub.verify_token is defined as "a subscriber-provided opaque token". This doesn't specify what an opaque token is in max length, allowed chars (alphanum only ? more ?), etc. Wouldn't the spec benefit from those additionals details ? [Unless "opaque token" is officially defined somewhere else and I missed it] Same applies to hub.secret. regards didier
