Indeed. For the benefit of other readers, the "master" files for UBL 
2.3 will be found at:

   http://docs.oasis-open.org/ubl/os-UBL-2.3/UBL-2.3.xml

Accordingly, the CVA file for UBL 2.3 will be found at:

   http://docs.oasis-open.org/ubl/os-UBL-2.3/cva/UBL-DefaultDTQ-2.3.cva

... and the internal links will point to the code lists found in:

   http://docs.oasis-open.org/ubl/os-UBL-2.3/gc/*
   http://docs.oasis-open.org/ubl/os-UBL-2.2/gc/*
   http://docs.oasis-open.org/ubl/os-UBL-2.1/gc/*
   http://docs.oasis-open.org/ubl/os-UBL-2.0/gc/*

... and so the relative references point *outside* of the UBL 2.3 
directory and so, in turn, point outside of the ZIP file. All one has 
to do is have each of the other UBL OS releases installed as sibling 
directories (as they are on the server) and then the CVA file works.

But, as Kees noted, the UBL 2.3 CVA file is but illustrative for the 
convenience of some users and to demonstrate the two-pass validation. 
It already has been created to produce the UBL-DefaultDTQ-2.3.xsl in 
the val/ subdirectory, so there is no need for the user to process 
the CVA file. Communities implementing their own two-pass validation 
would be taking on the responsibility to determine, manage, and 
package their own use of code lists.

Ummmmmm ... I don't think so if I've understood you correctly. The 
CVA file creates the Schematron using the coded values found in all 
of the code list genericode files. Not sure what "overwriting" is 
being done. Each time you replace the UBL 2.3 directory the CVA file 
will be pointing to the sibling UBL 2.x directories.

In your project you may decide not to use the demonstrative committee 
example but to create your own CVA file and your own collection of code lists.
