Re: Proposed resolutions for issues 146 and 150

Sanjiva,

The XML Schema looks fine except for a couple of minor errors. Here's a 
corrected version:

        <xs:attribute name="element" type="elementReference" />

        <xs:simpleType name="elementReference">
                <xs:union memberTypes="xs:QName">
                        <xs:simpleType>
                                <xs:restriction base="xs:token">
                                        <xs:enumeration value="#any" />
                                        <xs:enumeration value="#empty" />
                                </xs:restriction>
                        </xs:simpleType>
                </xs:union>
        </xs:simpleType>


However, I dislike the name of the attribute, elementReference, since the 
whole point of introducing it was to allow the case where there is no 
element reference. How about @messageBody or @bodyContent instead?

Looks good to me too .. however I'll let Arthur indicate an IBM
position as I can barely spell schiema let alone make value
judgements about the goodness of using unions.
