   Re: Schema validation

[ Lists Home | Date Index | Thread Index ]

Your schema includes a content model similar to the following in

  ( IDAH+ | CWG | ( IDAH+ , CWG) )

This is not allowed, by XML 1.0 in a DTD, and by W3C XML Schema in a
schema, because given an IDAH element in an instance, a processor
cannot immediately determine whether the first or the third branch of
the above choice is to be followed.

If you rewrite the above as

  ( CWG | ( IDAH+ , CWG?) )


   <xs:element ref="CommentWorkGrid"/>
    <xs:element ref="IndicationDaysAndHours" minOccurs="28" maxOccurs="28"/>
    <xs:element ref="CommentWorkGrid" minOccurs="0">

it will be OK.
