I don't think we should explicitly say the ontolex:LexicalForm is a
skosxl:Label. In fact, the lexical form represents the orthographic union
of surface forms of words, that is the same form (at least according to the
lemon definition, itself based directly on the LMF definition) can have
multiple strings (e.g., spelling variants, version in other writing
systems, pronunciations, segmentations, etc.) unlike a SKOS-XL label.

I can see ontolex:LexicalForm as a special subclass of skosxl:Label, which
captures all lexical information skosxl:Label does not.
In this way ontolex:LexicalForm is a natural extension of the (general)
standard.

Wrt the choice between the two for modelling WN, I think the decision
depends on how much WN information you want to capture.
The prolog version contains less information than the database files.
For the prolog version an orthographic union of surface forms is not
necessary. skosxl:Label will do, since WN prolog only contains canonical
synset elements.
I would only prefer to use ontolex:LexicalForm if you want to capture the
surface forms in the exception list files, which contain inflected forms
and base forms. Only ontolex:LexicalForm can capture this distinction.

Cheers,
Wim
