OWL is heavily using the new RDF collection syntax. Thanks for adding it.
However, there are a few places where it would be useful to have
collections, but where the collection syntax is not allowed.
The first case has to do with literals in collections. I believe that it
is not possible to have literals in the collection syntax, so that
 <owl:Class>
	<owl:oneOf rdf:parseType="Collection">
 1
	 2
	 3
	</owl:oneOf>
 </owl:Class>
is not legal RDF/XML. (Typed literals are also not possible.)
The second case has to do with making a collection directly an instance of
a class. For example, it would be useful to do something like
	<owl:AllDistinct rdf:parseType="Collection">
	 <owl:Thing rdf:about="#John" />
	 <owl:Thing rdf:about="#Mary" />
	 <owl:Thing rdf:about="#Susan" />
	 <owl:Thing rdf:about="#Joe" />
	</owl:AllDistinct>
This is not an official request to do anything, but these issues should not
be forgotten if there is any future work on RDF.
