Definitely No?

severity:

I share you estimation that it is difficult. I pointed out on 17.10. why 
  I think it more difficult than validating XML.

performance:

We only need validation during editing, not during content output. TS is 
some thousends lines. If we would work with flags for already validated 
code, the code that needs actual validation could maybe be reduced to a 
few lines.
