Description
Steve Hanson of IBM tested some of our schemas on github DFDLSchemas for compatibility with IBM DFDL.
He tested QuasiXML and CSV.
IBM DFDL does not implement encodingErrorPolicy="replace". We should consider whether we can change this to encodingErrorPolicy="error" without breaking things, or rather, we should change it, and see if too many things break. It would be helpful if every schema trying to be portable did not have to deal with this little detail.
These properties we don't implement yet are required by IBM DFDL, so without them defined in DFDLGeneralFormat our schemas can't be immediately portable to IBM DFDL even if everything "real" in them is portable. The properties are:
floating="no"
textBiDi="no"
calendarCenturyStart="53"
calendarObserveDST="yes"
Daffodil doesn't need these properties yet, but won't reject them I don't think, so we should include them to avoid portability hassles.
