This was there in the member submission, see Table 2 in 

  http://www.webont.org/owl/1.1/rdf_mapping.html

and, AFAIR, was one of the first things requested to be changed. :)

Actually, there is no precedence for having lists on the LHS, so I wouldn't like to follow this path.

And as a practical argument: This is not how I am accustomed to create OWL/RDF in a tool such as TBC: Start from some object (e.g. a property name), and attach predicate/value pairs to it. Here, you would need to start from some list, or apply some very different approach (don't know which one, perhaps predicate centric?).

Looks confusing to me. I would rather prefer

  q owl:superPropertyOfChain (SEQ p_1 ... p_n)

That's at least closer to a correct sentence, not so hard to remember, and expresses quite well what is actually meant.

Cheers,
Michael
