[x3d-public] reading schematron diagnostics

[Don Brutzman]

These Schematron alerts are readable if you split them up.  Here is explanation for first.

The above warning says that your ProtoInstance named "x3dconnector" has an initial field value named "startnode", but there is no corresponding field "startnode" defined in the governing ProtoDeclare named "x3dconnector".

No name found usually means that you have a flawed ProtoInstance.  Though the mismatch/misunderstanding might be in the ProtoDeclare or ExternProtoDeclare.  As author, you must ensure that all the names match.

This provides the location of the node in your scene graph.  Thus go to the X3D node, then the scene node, then the first ProtoInstance [1] , then the first fieldValue [1].

These are super helpful.  If the flaw is in your original X3D model, then stylesheets and other tools simply won't work - GIGO.

Good luck!

all the best, Don
