Please look closely at these standards. Asking a theory to recognize acceptable
and unacceptable sentences, actives and passives and so on is NOT controversial
nor theory specific. These are very ordinary demands that MUST be placed on any
theory of syntax. I am sure most people have assumed that every theory could
handle them.

Point taken. Please replace "this theory" with "these tools."

I am just referring to the need for a mention of extant materials.

Something like that, yes... Take a look at the rules of theories of syntax
that exist and then ask yourself if they can be implemented in a programming
langauge. The answer invariably is yes. Then take a look at the theories
themselves and ask yourself why this theory of the structure of language
(if it has indeed worked through all the problems) cannot meet the very
basic standards that I have proposed. Again. PLEASE do not reject those
standards out of hand. Look at them closely and ask yourself if there is
any theory of syntax that should be excused from them.
