Salve a tutti,
ho veramente bisogno di un consiglio : ho creato un xsd con openCMS, ma nel momento in cui cerco di creare il file xml associato mi da' il segiente errore ::

ErrorInvalid OpenCms content definition XML schema structure:
Element "/xsd:schema/xsd:complexType[2]/xsd:sequence/xsd:element[1]" attribute "minOccurs" value must be "0" not "1".

C'è qualche esperto che puo' darmi un suggerimento???
Ho ricontrollato un sacco di volte l'xsd, a me sebra scritto correttamente ....aiutoooo

Pertanto allego l'xsd relativo:::

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd"/>

<xsd:element name="ElementiMenu" type="OpenCmsElementiMenu"/>

<xsd:complexType name="OpenCmsElementiMenu">
<xsd:sequence>
<xsd:element name="ElementoMenu" type="OpenCmsElementoMenu" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>


<xsd:complexType name="OpenCmsElementoMenu">
<xsd:sequence>
<xsd:element name="Title" type="OpenCmsString" minOccurs="1" maxOccurs="1" />
<xsd:element name="Acronym" type="OpenCmsString" minOccurs="0" maxOccurs="1" />
<xsd:element name="Abbr" type="OpenCmsString" minOccurs="0" maxOccurs="1" />
<xsd:element name="Lang" type="OpenCmsString" minOccurs="0" maxOccurs="1" />
<xsd:element name="Path" type="OpenCmsVfsFile" minOccurs="0" maxOccurs="1" />
<xsd:element name="Hidden" type="OpenCmsBoolean" minOccurs="1" maxOccurs="1" />
</xsd:sequence>
</xsd:complexType>

</xsd:schema>
