Description Nam Nguyen 2006-09-20 02:35:50 UTC 
Currently AbstractDocumentComponent.resolveModel allow subclass to use namespace
as backup hint in resolving import/include/redefine constructs in xsd, wsdl,
bpel files.  Since the large percentage of namespace values does not actually
resolve to a real location, this usage has some impact on performance of
XAM-base systems depending on the underlying catalog implementations.  In
particular, the Retriever (xml/retriever) have background auto retrieval which
makes the impact more pronounced and more visible to IDE users.
Comment 1 Nam Nguyen 2006-09-20 02:39:26 UTC 
Since none of the IDE and non-IDE use cases needs to resolve references using
namespace as location hint, the fix to deprecated the usage of namesapce in the
API.  The default behaviour is only use the first hint for location and ignore
the backup hint.
