What exactly do you mean by "validate the grammar"?

In the past, you mentioned "the committee's desire to have a generally
LR(1) grammar", so I'm guessing "validation" = "confirmation that the
grammar is [generally] LR(1)". Is it anything beyond that? Are the
results of the ES3 grammar-validation archived somewhere? (Or are the
results simply "Yes"?)
