key & keyref problem (invalid XPath)

Hi,

I have several modular, included schemas that I xs:include in a 
'master' config schema so I can check constraints (key/keyref) across 
several configuration XML instances. Instead of using .//constr_elem, i 
want to start with the root node of the instance to better performance, 
e.g.
included_root_elem//constrained_elem

I am getting an error in both the Oxygen Xml editor and XMLSpy, but not 
in XSV from the command line. The helpful error message from Oxygen 
says:
c-general-xpath: The expression 'lsb:xsl//lsb:primary | 
lsb:xsl//lsb:dynamic_primary' is not valid w
ith respect to the XPath subset supported by XML Schema.

Using .//constr_elem does not give an error. Is this a bug in the 
editors (I hope so) or XSV? If in the editors, and there is an Oxygen 
developer here, is it possible to fix it? FWIW, I am using Oxygen (just 
downloaded the eval version) in Eclipse on OS X Panther -- it is a 
sweet editor!

The schema looks something like:

...
   <xs:include schemaLocation="site.xsd"/>
   <xs:include schemaLocation="xsl.xsd"/>
   <xs:element name="config">
     <xs:complexType>
       <xs:sequence>
         <xs:element ref="lsb:site"/>
         <xs:element ref="lsb:xsl"/>
       </xs:sequence>
     </xs:complexType>
     <xs:key name="lsb_primary_xsl">
       <xs:selector xpath="lsb:xsl//lsb:primary | 
lsb:xsl//lsb:dynamic_primary"/>
       <xs:field xpath="@id"/>
     </xs:key>
     <xs:keyref name="primary_xsl_idrefs" refer="lsb:lsb_primary_xsl">
       <xs:selector xpath="lsb:site//lsb:page | lsb:site//lsb:folder | 
lsb:site//lsb:site"/>
       <xs:field xpath="@lsb:xsl"/>
     </xs:keyref>
   </xs:element>
...

thanks,
-Rob
