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.

..dan

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,
                Tony.
