It is useful to be notified after an Inline has completed loading.
<br> This is especially true for external access to the scene if the Inline
<br> has exports (or dom style access is used).
<br> A LoadSensor generates such an event:
<br>
<br> <a href="https://www.web3d.org/documents/specifications/19775-1/V4.0/Part01/components/networking.html#LoadSensor">https://www.web3d.org/documents/specifications/19775-1/V4.0/Part01/components/networking.html#LoadSensor</a>
<br>
<br> "The isLoaded field generates events when loading of the LoadSensor's
<br> children has completed."
<br>
<br> However, in the case that the Inline contains another Inline itself a
<br> question came up. Is loading considered complete when the outer Inline
<br> xml/json/.. is completely downloaded but still has only a url
<br> reference to the inner Inline ? That typically would happen before
<br> also the inner Inline is completely downloaded. Or should the event be
<br> generated only after the inner Inline (and all of its content) is also
<br> completely downloaded ?
<br>
<br> The second option is more useful, especially for web use where loading
<br> generally occurs asynchronously and such events are often used to
<br> initiate processing of downloaded content.
<br>
<br> For generic X3D use, one could imagine a situation where a LoadSensor
<br> triggers something which assumes that the scene is fully rendered
<br> before an Inline is actually rendered.
<br>
<br> It is also related to how EXPORT/IMPORT works. One could probably
<br> construct a situation where a LoadSensor triggers access to an
<br> EXPORTed node from an inner Inline before it is available.
<br>
<br> Is a tightening of the language necessary ? Perhaps there is already a
<br> more precise definition of 'loading' in the spec. somewhere else ?
