[x3d-public] X3D example scenes using MetadataSet in WorldInfo

[Brutzman, Donald (Don) (CIV)]

Hi Vince.  I belatedly found the attached scene lingering on my desktop.  Looked like the goal was to show nested MetadataSet nodes.

I've added some information to the scene, and validated them.  Also adapted matching side-by-side versions for X3D3 and X3D4 to illustrate small differences in syntax.

<WorldInfo>
    <!-- WorldInfo single available child field of interest is 'metadata' and so contained MetadataSet must have containerField='metadata' which IS the default in X3D3' -->
    <MetadataSet containerField='metadata' name='birthday' reference=' http://www.americaslibrary.gov/jb/colonial/jb_colonial_washingtn_2.html '>
        <MetadataString containerField='metadata' name='calendar' reference='this node describes nature of parent node, and is not intended as a data value' value='"Julian"'/>
        <!-- MetadataSet next field of interest is 'value' and so contained Metadata nodes must have containerField='value' which IS NOT default in X3D3' -->
        <MetadataInteger containerField='value' name='day' value='11'/>
        <MetadataInteger containerField='value' name='month' value='2'/>
        <MetadataInteger containerField='value' name='year' value='1731'/>
    </MetadataSet>
</WorldInfo>

Hopefully that is moving in the directions you want, let's keep improving.  Thanks for initiating this effort.

all the best, Don
