If I remember correctly, there was a concern expressed by some users about 
an inability in XSD 1.0 to succeed in restricting certain complex types 
when the content models involved more than one namespace.  I don't think I 
can reproduce an example offhand, but I'm fairly sure that was the 
original motiviation.

        Subject:        [XML Schema 1.1] What problem is this solving: the 
ability to  define multiple targetNamespaces in a single schema



Hi Folks,

In XSD 1.1 a schema can have multiple targetNamespaces. Presumably this 
capability was introduced to solve a problem. What problem is it solving?
