the VRML loader stores the original VRML fields in an attachment (with
dynamically added fields). The OSB writer can write those out, but it
can not load attachments with dynamic fields back in ATM.
However, the VRML attachment is marked as internal, which should cause
the OSB writer to ignore it, but it doesn't, so that is definitely a
bug. I'll work on a fix.
Cheers,
Carsten
