I think that would be good.

I see use-cases where it would be useful to suppress these data errors. For
example, for exploratory work with a database schema as a mapping is being
developed. I think it would be acceptable for R2RML processors to have
options that allow these data errors to be suppressed.  I don't think we
need to do anything in the spec to enable this. It is just another mode
that a specific R2RML processor can be used in.
