I believe that the xml:base in the Editor's Draft of wine.owl and
food.owl is incorrect. For example, wine.owl has:

xml:base  = "http://www.w3.org/2001/sw/WebOnt/guide-src/wine#"

The example of xml:base in the RDF/XML syntax specification (Jan 23,
2003), Sect. 2.14 [1] does not have a '#' after it, and also says that
the relative URI reference of an rdf:ID is formed by adding a '#' in
front of its value. Although, I can find nothing definitive on this (I
spent 1/2 an hour looking and gave up), it appears that the '#' at the
end of our xml:base is at best redundant and at worst could create
absolute URIs of the form:

http://www.w3.org/2001/sw/WebOnt/guide-src/wine##hasMaker

(notice the double '#' signs)
