[Exist-open] handling same path but multiple namespaces depending on data provider

[Guillaume M. <gui...@un...>]

Hello,

   I have a module which consumes VOTable (table/tr/td with meta data 
for Astronomy) using a standardised TableAccesProtocol. But depending on 
the data provider the returned document may get multiple namespaces 
depending on the version they implement, eg.:

declare namespace votable="http://www.ivoa.net/xml/VOTable/v1.2"; (: 
could be v1.3 v1.4 :)

Most data part are the same in the various versions and I would like to 
support it dynamically without branching/duplication/copy.

I tried with the wildcard namespace using *:tag but didn't investigate 
to know more about performance issues.

Is there any best practices, hints or documentation pointers for such 
use case ?


Cheers,
