This is very abstract, and that makes me doubt its helpfulness. A concrete mechanism for why the validation errors might not be noticed would make this much more helpful. For example the fact that the provided informative schemas treat some datatypes e.g. time expressions as generic text strings could result in false positives when a non-conformant string is present.

By the way, using the current TTML schemas typically generates false negatives when using semicolon-delimited lists of values in style attributes in an animation context, except where the schema just defines the syntax to be a string.

Thanks for pointing this out. Perhaps I will swap it for the current discussion that uses an RNC example.
