RE: [x3d-public] LoadSensors: create via SAI? Monitor an ExternProto?

["Tony Parisi" <tparisi@mediamachines.com>]

I remember discussing with Justin the possibility of the Browser object
generating events for when EXTERNPROTOs are loaded. However I'm not sure
anything came of that?

I also recall that we removed the restriction requiring the EXTERNPROTO to
be loaded synchronously before continuing processing the world. This in fact
is the source of Dave's current dilemma. However I just took a look at the
spec again, and I don't see any specific language defining whether
EXTERNPROTO loading is synchronous, asynchronous or browser-defined.

Anybody have any clues?

Tony
