Re: [higgins-dev] new IdASRegistry

>[Markus] The cache is very simple. If it is enabled, the instances never become stale. The idea is that if the IdASRegistry is configured from a local file, you enable caching, since you don't expect the file to change. If you configure the IdASRegistry from a URI or XRI, you disable caching, so every time a context factory is requested, the XRDS is freshly discovered and a context factory chosen, instantiated and configured.

Maybe it would be good to make IContextFactory define a getInstance method that is called, and thus each CP could control its own cache and staleness.  I think this is something we don't need to address right now.
