[ttml2] Clarify that [validate document] may have false {negatives, positives}.

skynavga has just created a new issue for https://github.com/w3c/ttml2:

== Clarify that [validate document] may have false {negatives,positives}. ==
Add note under ยง5.3.1.2 [validate document] that, since the effective validation schemas are implementation dependent, that false negative or false positive results may occur. In particular, describe false positive example where the use of `#prohibited` in a content profile does not necessarily lead to a validation error in the case that a prohibited feature is used in a document, but the effective validation schemas were overly general in their definition.
