[dsdl-discuss] Re: Concurrent (overlapping) structures

Eric

>I'd say that, more generally, any technique such as JITTSs
(http://sbl-site2.org/Extreme2002/) which can build several XML infosets
through transformation of a source document should be easy to integrate
using our Validation Management (ex framework).
Should we add this as a use case?

While I think this is a useful case to be added to the list, I don't think
its the same case as Alex is talking about. Remember that for applications
such as loose-leaf publication you need to keep two concurrent structures,
one for the logical data and one for the presented data. In this case what
we need is to be able to take two subsets of information out of a single
dataset, without any transformation. OK, so we can do this by assigning
separate namespaces to the different datamodels, but what happens if these
two datamodels do not overlap cleanly. SGML had an answer to this problem.
XML does not have an answer, and neither does RELAX NG. What we really need
is a mechanism that says "ignore any markup in namespace X and parse against
my first model, then ignore any markup in namespace Y and parse against my
second model".
