you can get into child context by the DEF name.

This may be a little too concise for me to get.

Here is the situation:

Main.x3d:

...
<Inline DEF='animatedHat' url="'hat.x3d'" />
...

hat.x3d:

...

<ROUTE fromNode='ts' ... />

...

Pseudo code using SAI external to Main.x3d:

mainScene = getBrowser().currentScene

//mainScene.addRoute(someRoute) is available

inlineNode = mainScene.getNamedNode('animatedHat')

inlineScene = inlineNode.getInternalScene() // is something like this in
the SAI ??

tempRoute = inlineScene.addRoute(fromNode...)

....

inlineScene.removeRoute(tempRoute)


Is something like getInternalScene() in the SAI standard ? I think maybe
not.
