Notes
-------------------------------------------------------

  The exception to this rule is when S and O have the same
  morphological form both when being a direct object and an indirect
  object, i.e. in the case "Matj ljubit dochj", with matj[CASE nom]=
  matj[CASE acc] and dochj[CASE nom]=dochj[CASE acc], in which case
  the SVO order is required.

Is this a prescriptive rule or a descriptive generalization?

  Like in English, pronouns don't typically occur with determiners
  (author, this info is not found in our references).  For example,
  "jetot on" ("this he") is an ungrammatical phrase, but "jeta kniga"
  ("this book") is grammatical.  But we are not dealing with
  determiners occurring with pronouns for this Lab yet, i.e. we model
  the pronouns as nouns, also specifying their determiner feature as
  optional:

Actually, you should just say that determiners are impossible
with pronouns.

  Russian has 6 cases (nominative, genitive, dative, accusative,
  instrumental, prepositional (locative)), each of which is marked
  morphologically on the noun.  Examples #15 through #26 illustrate
  the use of the case system in Russian.  The choice of the case
  marker depends on the class that the nouns belong to.  For example,
  the nouns "sobaka" and "kniga" belong to the CLASS II nouns with
  hard stems, i.e. in they will have suffix (ending) "e" in Dative
  case, as in example #19 below.  In #20 the case marker is not a
  Dative case marker and the sentence is ungrammatical.

But which option did you pick on the case page?

  In Russian determiners are optional; they come before the NP and
  adjectives can come after/before NP, so we have only one grammatical
  case.  If we place determiners after the NP, the sentence will still
  be grammatical because then they will be considered to be
  adjectives. Thus, the only example that we have in Test Suite for
  the Lab2 is a grammatical example #27 below, in which the determiner
  precedes the noun.

Determiners and adjectives are both part of the NP, so they can't
come after/before it.  I think you mean after/before the head noun.
What is the relative order of determiners and adjectives?  By "considered
adjectives", do you meant that the meaning changes?

So far all sentences in the test-sentences section (#1 through #5, see below) are parsed correctly.

section=test-sentences
  sentence1_orth=Ivan kupil sobaku.
  sentence2_orth=Sobaku kupil Ivan
  sentence3_orth=Ivan kupil knigu
  sentence4_orth=Ivan spit
  sentence5_orth=Ivan letit samoljotom

You're supposed to be testing over the test suite you are creating ---
all 27 examples in testsuite.txt.

You need some examples of accusative case in simple transitives,
since we won't get to ditransitives.  You should also have some examples
showing that accusative case is required there.
It would also be good to have test suite examples with your
nom-instr transitive pattern.

All pronouns should have the same rel:

    noun3_stem1_pred=_he_n_rel

should be _pronoun_n_rel.

Where are the rest of your pronouns?
