validating a XML file using XSD 1.1 with Xerces-J

Hi,

    I am trying to write a XSD 1.1 schema that uses  XSD 1.1
assertions. I am able to repeat the examples described in the URL:
http://mukulgandhi.blogspot.com.es/2009/11/xsd-11-some-xsd-11-samples-running-with.html
so I guess my xerces-j installation is OK.

   When I tried to include an assert in my schema (I reproduce part of
it in the email and attach the full file) I got the error message:

[Error] kk.emx:33:14: cvc-assertion.3.13.4.1: Assertion evaluation
('defocusU ge defocusV') for element 'particle' with type '#anonymous'
did not succeed.

but defocusU is indeed greater than defocusV

Note that the commented lines

<!-- <xsd:assert test="t34 le 3" />-->
<!-- <xsd:assert test="@index le 3" />-->

work properly when uncommented

but

        <xsd:assert test="defocusU ge defocusV" />

does not. I guess the problem is that defocusU and defocusV are complextypes

any help will be welcomed

    thanks

               Roberto
