[x3d-public] Scanner Metadata Example models, X3D Schematron name warning adjustment

[Don Brutzman]

Revised example online:

* X3D Example Archives: X3D4AM, X3D for Advanced Modeling, Scanning, Scanner Metadata Example 33
   Embed example metadata associated with a scanned 3D model using X3D version 3.3
   https://x3dgraphics.com/examples/X3dForAdvancedModeling/Scanning/ScannerMetadataExample33Index.html

Similarly an example for X3D4 is provided, in anticipation of possible testing of changed containerField defaults for metadata nodes.

In X3D Schematron, have also made either relaxed or strict the warning for name values that include space characters.  This should match the strict typing of X3D DOCTYPE and X3D XML Schema.  Rules can be found summarized at

* X3D Scene Authoring Hints, Naming Conventions, Typing of name attributes:

all the best, Don
