Maybe I'm missing something here, but so far as I see it, plugins 
obviously need to be concerned with the settings format.  They have to 
receive and process settings and they have to produce them.

So far, a few possible schemes have been suggested.  The data can be 
completely under the control of the host and simply a snapshot of 
parameter values.  In that case, the plugin need not know anything about 
the settings format, however, no one's going to agree to that since it's 
clearly not sufficient for a lot of plugins' needs.  Another possibility 
is totoally opaque data blocks, which the plugin needs to know about; in 
fact, the plugin is the only one who understands it.  And another 
possibility is some sort of data format, which could be defined as a 
data structure, a data block with tags, or a keyed XML structure.  So 
anyway, if the plugin is provided with a keyed XML data block, it 
certainly will need to know that it's a keyed XML data block, otherwise 
what will it do?

That's what I see, but again, maybe I'm misunderstanding the issue...
