Jonathan

Feel free to add your original point, namely that Schema Definition Warning only appears once, as a public comment.

RecoverableError is not appropriate here. The problem is with the schema not the data.

On second thought, instead of a Schema Definition Warning, could this be a recoverable error instead? That is, would the following convey the originally intended meaning better?

Note: Unrecognized DFDL properties or property values can produce a recoverable error, and an implementation can attempt to process data despite the error.

IIRC, this section on specific errors was added *before* recoverable errors were added to the spec.

Thoughts?

The phrase "Schema Definition Warning" only occurs once in the published 1.0.4 spec (without respect to capitalization), in Section 2.6 Specific Errors Classified:

"Note: Unrecognized DFDL properties or property values can produce a Schema Definition Warning and an implementation can attempt to process data despite the warning."

Is the concept of a Schema Definition Warning a nascent concept already present in the spec but not well-defined? If so, this might be a minor issue that warrants an errata. My recommendation would be that Schema Definition Warning be defined and used consistently throughout the document.

Otherwise, I recommend that "Schema Definition Warning" be replaced in the above sentence with simply "warning". In this case, this is probably just an editorial issue.
