Content of the grammar compiled when working with a corpus

When using SEMCONST, it is possible to compile a subgrammar only containing tree families expected to cover the corpus. In that case, a new valuation file is computed from the lexicon and the initial valuation file.

If the lexicon ask for the evaluation of a given tree family which is not asked for evaluation in the original valuation file, then the SEMCONST does not consider this family.

In other words, in case of dissension between the lexicon and the initial valuation file, the latter wins.
