Hi,

I'm a little confused by Req 88 ... "Plugin metadata must be available
without loading/linking a plugin dll"

This implies that plugin metadata might be stored externally to the dll.  I
assume this is a performance hack, the assumption being that the host can
enumerate plugins faster if it doesn't have to load/link each one in order
to probe it's capabilities.
   How can an external file describe a plugin, when the plugin's IO and
parameter list is potentially 'dynamic'? ( Req 53:   Plugins must be able to
perform seemingly spontaneous parameter changes. )

Secondly, it's dangerous to have two ways of querying a plugin ( 1-
directly, 2 - via an external file).. which is authoritative?, what if the
two do not agree?

Lastly, there are better ways to achieve the performance gain.  Cubase, for
example, queries all plugins just once, and stores the results in a single
database.  The host never needs probe a plugin again (except new ones).

I suggest there be one mechanism for querying plugin configuration, by
loading/linking and querying it directly.  It's simple and foolproof.

Jeff
