Re: Combining maxOccurs="unbounded" with all indicator

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
