validator - event, argument structure and aspect

[Marketa-Lopatkova]

1. Predicative nouns have their own argument structure but not aspect
   Czech example: podnět (as in podal podnět vůči něčemu 'to file a complaint against something/somebody') can be seen as a predicative noun that form the meaning of the whole light verb construction. It is the noun which brings its participant to the structure, so it it should have its own argument structure. At the same time, it is not clear which lexical verb can be used instead of the light verb construction.
   On the other hand, predicative nouns does not typically encode aspect.
   English example: note (as a noun) is listed in the PropBank with ARG1 (frame note-02), with 2 examples note
   of the growing problem of computer fraud and little note of this development

2. Abstract predicate say-91
   Thus abstract predicate should "be used for unattributed speech in dialogues, etc-- anywhere there is not a predicate of speaking in the surface sentence. Also for 'according to X, Y', in English" (from UMR lists).
   This, it is probably the right way how to annotate prý 'reportedly' in Czech.
   However, in this case, it has no aspect value?

3. event as a place-holder
   The PDT2UMR automatic conversion uses the "event" label to replace #EmpVerb. The aspect attribute seems not relevant here (the same for modal-strength).
