Hi Thomas,

> While you're at it, here is a couple of things I spotted

Thanks a lot for the report! Much appreciated.

The issue is that it is a W3C policy to never change what is in the http://www.w3.org/TR/ namespace. It would require a new working group to update these recommendations...

What I'll do is to suggest an item for these three editorial issues to be added on the SKOS documentation Errata:

>   * Exemple 77 uses "love"@fr while it should be "amour"@fr;

Well spotted!

>   * Section C5 states : "This RDF schema document expresses the SKOS vocabulary" while I think it should read "This RDF schema document expresses the SKOS*-XL* vocabulary";


>   * S48 and S58 are categorized in "Class and Property Definitions", but they are expressing "disjointWith" relationships. Shouldn't they belong to an "integrity condition" section like the other "disjointWith" statements in the recommendation ?

Yes, I guess than at the time of writing we did not pay too much attention to where these SKOS-XL axioms were. this section existed as an independent document before being integrated as an annex.

> while working on a translation of the recommendation :

By the way if you have a translation, please share it. Right now the W3C translation database seems down. But W3C does collect them and gives access (it is one of the first links on the W3C documents, actually).
