Greetings. 

I was really thinking of something which might be
more tricky: Having a namespace for the
xpath-file schema is probably necessary but then
we also need a namespace, I believe, for every list
of XPaths (hopefully in XML, hence the relevance
of a namespace) for every UBL document type.

I'm thinking of a namespace, that is, not applied to
a W3C Schema as usual but applied to an XML instance
which functions like a schema. It would therefore 
mean, I think, creating our own root element attribute
called namespace and having a uri as its value. This
is if we are going to have a set of files in XML which
each list the XPaths of the SBS of a UBL Document.
It is these files which I'm thinking would need the
namespace and possibly version attributes for the
root element
e.g.
<(prefix):(root element name)
xmlns:(prefix)="urn:oasis:names:tc:ubl:sbsc:xpath"
namespace="urn:oasis:names:tc:ubl:sbs:xpath:Order-1.0"
version="1.0-beta-2">

We'd therefore still need a set of uri's and appropriate rulings
about them - one uri for the namespace of the Schema of
the xpaths lists and others for the xpaths list themselves.

All the best

Steve

Do you mean by this question "can we put the vocabulary into a particular 
namespace"?

Sure, but it will take some time for me to change my Python programs to be 
namespace aware.  Maybe I can just cheat and leave everything in the 
default namespace since these tools are interim tools until other tools 
generate the XPath information.

I didn't realize that non-namespace vocabularies were not allowed.

Okay, next question ... probably to the SSC ... what are the UBL policies 
for choosing namespace URI strings for subcommittee projects?  Maybe I 
should ask this of the TC.

How about something like:

   urn:oasis:names:tc:ubl:sbsc:xpath
