[x3d-public] instantReality has incorrect syntax for EXPORT statement

[Don Brutzman]

Bug report

1. The attached scene, maintained at

	http://www.web3d.org/specifications/java/examples/HelloWorldProgramOutput.x3d

includes the statement

         <EXPORT AS='WorldInfoDEF3' localDEF='WorldInfoDEF'/>

which appears to be legal according to

	9.2.6 EXPORT statement
	http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/networking.html#EXPORTStatement

However instantReality reports

=======================

=======================

it looks like your element 'IMPORT' is looking for an obligatory attribute 'exportedDEF' but that is incorrect (that might have been the initial name when first proposed).

The correct attribute is 'AS' and usage is optional.

	X3D v3.3 DOCTYPE documentation: EXPORT
	http://www.web3d.org/specifications/X3dDoctypeDocumentation3.3.html#EXPORT

	X3D v3.3 Schema documentation: EXPORT
	http://www.web3d.org/specifications/X3dSchemaDocumentation3.3/x3d-3.3_EXPORT.html

2. Support for the class attribute and UNIT statement would also be appreciated.

	4.3.6 class attribute syntax
	http://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#ClassAttributeSyntax

	7.2.5.5 UNIT statement
	http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/core.html#UNITStatement

(syntax for .x3d encoding is 'unit')

	X3D v3.3 DOCTYPE documentation: unit
	http://www.web3d.org/specifications/X3dDoctypeDocumentation3.3.html#unit

	X3D v3.3 Schema documentation: unit
	http://www.web3d.org/specifications/X3dSchemaDocumentation3.3/x3d-3.3_unit.html

3. I think the ArtDeco02 prototype is working OK, not sure what those unregister diagnostics are.  Also the warning "Invalid Field name description in fieldValue" appears to be incorrect, there is a field name description that is properly declared and re-initialized using fieldValue.

4. Ongoing validation testing of this developmental scene remains available at

Thanks for your efforts with InstantReality, it is really great.

all the best, Don
