Template creation in BI Publisher

Question

I have an issue while creating template document in OPM. I have exported the schema (xsd) and created a new rtf document template in OPM. I edit the template to add some attributes (public) into it. I clicked on 'XML Schema' in BI Publisher tab and chose the exported xsd file which has all the attributes in it. I got the message box that says 'Data Loaded Successfully' followed by a window with all the attributes list.
Now the problem starts. When I click on 'ab|Field' tab to add some attributes to my page, it opens up a window but no attributes are listed in it. Anyone got some idea what is happening here?
My xsd is as follows:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="global-instance">
<xs:complexType>
<xs:all>
<xs:element name="a1_value" type="xs:string" />
<xs:element name="a1_text" type="xs:string" />
</xs:all>
</xs:complexType>
</xs:element>
</xs:schema>
And the filed window has the following fields
Schema
@xs
Element
@name
Complextype
All
Element
@name
@type

Thanks Kevin for your reply.
I unstalled 11.1.1.6.0 version of BI Publisher and installed the version 11.1.1.5.0 and now when I click on 'XML Schema' in BI Publisher tab, nothing is happening. I can see the ab|Field tab is enabled even before loading some schema. But when I click on it, says 'Automation Error Unspecified error'.
Any idea what is happening?
