Boris Kolpackov closed XERCESC-1721.
------------------------------------

    Resolution: Invalid

The all compositor cannot be inside the sequence compositor. If you remove the <sequence> tags in the referencing type, the schema becomes valid.

>             Project: Xerces-C++
>          Issue Type: Bug
>          Components: Validating Parser (XML Schema)
>    Affects Versions: 2.7.0
>         Environment: Windows XP
>            Reporter: Bill Yan

> When a group is defined with Order indicators "all", and this group is refered in a complexType definition, the schema file looks like this:
> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
>  <xsd:element name="comment" type="xsd:string"/>
>  <xsd:group name="schemaTop3">
>   <xsd:all>
>       <xsd:element ref="comment"/>
>    </xsd:all>
>  </xsd:group>
>   
>  <xsd:complexType name="PurchaseOrderType">
>   <xsd:sequence>
>    <xsd:group ref="schemaTop3" minOccurs="0" maxOccurs="0"/>
>   </xsd:sequence>
>  </xsd:complexType>
> </xsd:schema>
> when I use XercesDOMParser::loadGrammar() to check the validity of this schema file, the following error info is reported: 
> "A group whose content is 'all' must only appear as the content type of a complex type definition. - Line 11, Col 61".
>  I tried to change xsd:all to xsd:sequence or xsd:choice, no error is reported.
