Re: [xml-dev] Problem using <xsd:all>

[George Cristian Bina <george@oxygenxml.com>]

Hi Paul,

Use a choice
(success,failure)|(failure,success)

in XML Schema:

<xsd:choice>
   <xsd:sequence>
     <xsd:element ref="tasklist:success"/>
     <xsd:element ref="tasklist:failure"/>
   </xsd:sequence>
   <xsd:sequence>
     <xsd:element ref="tasklist:failure"/>
     <xsd:element ref="tasklist:success"/>
   </xsd:sequence>
</xsd:choice>

Best Regards,
George
