Another bug on JAXB

I'm getting the error:
            unexpected attribute "guid"

when using the schema below.

There is a definition used as a "supertype" (FilesetType) and two other
types are based on it: "RulesetType" and "EnumsetType"
But both require the guid attribute, since the attributed is defined in the
"supertype".

The document to get the error would look something like:

<package>
      <filesets>
            <enumset guid="CAFECAFECAFECAFE" name="something"
description="something/>
            <ruleset guid="CAFECAFECAFECAFE" name="something"
description="something>
                  <load resource="\some\path\here"/>
            </ruleset>
      </filesets>
</package>

Here is the schema:
