Hi Frans,

Your DTD model:
(title | Action | ActionList | Separator | WeakSeparator |
TearOffHandle | Merge | MergeLocal | DefineGroup | Menu )*

in XML Schema will be:

<xsd:choice minOccurs="0" maxOccurs="unbounded">
   <xsd:element ref="title"/>
   <xsd:element ref="Action"/>
   <xsd:element ref="ActionList"/>
   <xsd:element ref="Separator"/>
   <xsd:element ref="WeakSeparator"/>
   <xsd:element ref="TearOffHandle"/>
   <xsd:element ref="Merge"/>
   <xsd:element ref="MergeLocal"/>
   <xsd:element ref="DefineGroup"/>
   <xsd:element ref="Menu"/>
</xsd:choice>

Best Regards,
George
