Subject: Re: [ubl] Groups - unvalidated-code-lists.zzz uploaded


In looking at unvalidated code lists, one thing I didn't mention is that  
both MDDL and FpML (both financial MLs) use unvalidated code lists.  They  
both use the (FpML) 'scheme' construct.  As an example, in an MDDL  
document you would see things like

<code scheme="http://www.example.com/code-list-X";>XXX</code>

where the 'scheme' attribute is a URI which uniquely identifies the code  
list from which the code is taken.  No attempt is made to provide code  
list validation within the MDDL Schema.  The advantage of this approach is  
that it allows users, within their instance documents, to specify which  
code list they are using.  If the 'scheme' is not provided, it (usually)  
defaults to a URI which identifies the most commonly used code list for  
that code.

The disadvantage is that, to date, neither FpML nor MDDL provide a  
solution for users that implements a second stage validation to check the  
code lists, so it is an "exercise for the user".

Cheers, Tony.
