[pubsubhubbub] Re: 7.3 Content Distribution

[Jay Rossiter]

I don't see what functionality would be restricted by defining that hubs couldn't change content that they don't maintain as part of the protocol.  If I'm missing something, please enlighten me.     I have always been of the opinion that the "message content" is every attribute of that content.  If someone who is not me changes anything that is in that feed, they are changing the message content.  Some content may be intended for machines instead of humans, but the fact that I took the time to add a <foo:bar/> tag to my item may have very important meaning to someone/thing reading it.     Except as necessary to support the propagation of content to subscribers (e.g. removing items so that only deltas are published, adding atom:source tags for aggregation, etc.), I can find no reasonable case for the hub making modifications to the feed.
