[x3d-public] JSON encoding for SFNode: no [array brackets]

Fri Feb 19 08:51:43 PST 2016

As you suspected, the .x3d is not passing QA tests for XML validation because no DOCTYPE or schema is linked.  Once that is done, further flaws may be found.

I used X3D-Edit to insert the following:

<!DOCTYPE X3D PUBLIC "ISO//Web3D//DTD X3D 3.3//EN" "http://www.web3d.org/specifications/x3d-3.3.dtd">
<X3D profile='Immersive' version='3.3' xmlns:xsd='http://www.w3.org/2001/XMLSchema-instance' xsd:noNamespaceSchemaLocation='http://www.web3d.org/specifications/x3d-3.3.xsd'>

Now passes more cleanly, only reporting warnings about missing description fields.

Gotta go, converting updates to JSON with our latest changes can be later.

all the best, Don
