EXI Special case grammar processing

Good Afternoon,

 

I am a student at NPS trying to build an implementation of EXI to
prove/disprove its value to DoD. I am stuck on how to process nested
elements with same Qname as in the example XML  below. I cannot find
where in the specification this is explained/implied.

 

Is each Transform a new grammar, or are they all the same grammar?
Either way, how should this be processed. Perhaps this would make
another good example file for the specification.

 

 

 

<?xml version="1.0" encoding="UTF-8"?>

<X3D>

    <Transform rotation='1 0 0 0.4'>

        <Transform rotation='0 0 1 0.5'/>

    </Transform>

</X3D>

 

 

 

Any guidance is appreciated.

 

Thank you,

 

Sheldon
