If I read you correctly, this should never have worked.
You've asserted in your schema that <name> has _a_ unique value for
each <obj> under <object_space>, but this is manifestly untrue.
If what you meant was that its value is unique for each <name> under <obj>,
then you need a different declaration, namely:
<xsd:unique name="unique_obj_name">
<xsd:selector xpath="name"/>
<xsd:field xpath="."/>
</xsd:unique>
which would be contained within the element decl for <obj>.
If you want to say that its value is unique each <name> under <object_space>,
then you need
<xsd:unique name="unique_obj_name">
<xsd:selector xpath=".//obj/name"/>
<xsd:field xpath="."/>
</xsd:unique>
which would be contained within the element decl for <object_space>.
