Description

Recent work on a DFDL schema for Praat TextGrid this was observed on the DFDL WG mailing list

1) IBM DFDL validates the DFDL schema before parsing and it found some missing properties. The DFDL specification says that if a schema object needs a property then you must provide a value, there are no build-in defaults. The missing properties are:
- textBidi="no"
- floating="no"
- encodingErrorPolicy="error"
Daffodil is presumably not reporting their absence as an error, which strictly speaking is non-compliance with the DFDL spec.
If you add them into your dfdl:defineFormat then the errors go away.
