In this blog post, the author describes the differences between SKOS and SKOS-XL. Includes a brief example (in Turtle syntax) of a SKOS-XL representation with extra properties adding metadata to some of the labels describing entities in a dataset. He explains that this would not be possible in regular SKOS, because there labels are considered strings (or, sometimes, "lexical entities") and are not allowed to posses such properties of their own.
