Hi Mike,

The XML Schema xlink.xsd only defines attributes and attributeGroups so
seeing no class generated from it is the correct behavior. 
The warning message is output each time Castor encounters a <import>
statement without really knowing if it is really needed to generate
sources for the imported schemas.

Besides according to the xlink Schema, the simpleLink attribute is
defined as below:

<attributeGroup name="simpleLink">
    <attribute name="type" type="string" fixed="simple" form="qualified"
/>
    <attribute ref="xlink:href" use="optional" />
    <attribute ref="xlink:role" use="optional" />
    <attribute ref="xlink:arcrole" use="optional" />
    <attribute ref="xlink:title" use="optional" />
    <attribute ref="xlink:show" use="optional" />
    <attribute ref="xlink:actuate" use="optional" />
</attributeGroup>

So the output of type="simple" is correct. However there might be a
problem of namespace declaration. Can you please post the XML Schema you
use and a simple as possible test case that demonstrates the problem for
further investigation?

Thanks,

Arnaud
