RE: [ubl] The trailing-space bug

Title: Re: [ubl] The trailing-space bug

My organization has taken a 
slightly different stance on these problems. 

 

First we try to keep to the 
"core" features of schema (similar to what has been done here) and not try to 
work on the edge. But even some of what we consider core has been implemented 
differently. We feel that as long as I have a working implmenetation in the Unix 
and MS world that we are ok. No need to have complete support - it is then up to 
the users of these other tools to identify these issues to their vendors or 
developers of the tools they use. 

 

We have found Xerces-J and 
MS-XML release to be pretty consistent for the features we currently use. It 
also happens that Spy is also currently in line with our expectations, but in 
past versions it has not been. Note that we have found different issues with the 
MS .Net parser that do not occur in their COM? version.

Arguably none of the tools is 100% conformant (it's like ALGOL 
69 all over 
again).  However, XML Spy commands a large market 
share, and *those* folks 
think it is 100% conformant.  On that 
basis, just as it would be a bad 
idea to *only* validate with Spy, it 
would also be a bad idea to send out 
UBL Schemas/XML-files that *don't* 
validate with Spy (sub-issue is that 
different versions of Spy may 
behave differently, but let's do what we 
can).

My experience is 
that the only way to do a Schema that works for an 
acceptable share of 
the market is to validate against as many Schema 
validators as 
possible, and only use features/constructs that work with 
all of 
them.

Java-based editors (like Topologi) generally use Xerces-J for 
validation, 
and the Schema-WG seems to feel that this is currently the 
most correct of 
the 
validators.

        
Cheers,
