xml - How to add attribute on element level in xsd -

i want genearte kind of xml using xsd

<unassignedsecurityroleusers>     <username errorcode= "1" errormessage="">?</username>     <username errorcode= "1" errormessage="">?</username>     ....     .... </unassignedsecurityroleusers> 

i tried first

<xsd:element name="unassignedsecurityroleusers" type="unassignedsecurityroleusers"/> <xsd:complextype name="unassignedsecurityroleusers">       <xsd:sequence>           <xsd:element name="unassignedusers" type="unassignedusers" minoccurs="1" maxoccurs="unbounded" />     </xsd:sequence>  </xsd:complextype>  <xsd:element name="unassignedusers" type="unassignedusers"/>   <xsd:complextype name="unassignedusers">       <xsd:sequence>           <xsd:element name="username" type="xsd:string" minoccurs="1" maxoccurs="unbounded" />     </xsd:sequence>      <xsd:attribute name="errorcode" type="xsd:string" />     <xsd:attribute name="errormessage" type="xsd:string" />  </xsd:complextype> 

but generate this

<unassignedsecurityroleusers>       <unassignedusers errorcode="" errormessage="" >         <username></username>     </unassignedusers>       <unassignedusers errorcode="" errormessage="" >         <username></username>     </unassignedusers> ... .... </unassignedsecurityroleusers> 

if use

<xsd:element name="unassignedsecurityroleusers" type="unassignedsecurityroleusers"/>     <xsd:complextype name="unassignedsecurityroleusers">       <xsd:sequence>           <xsd:element name="username" type="xsd:string" minoccurs="1" maxoccurs="unbounded" />     </xsd:sequence>      <xsd:attribute name="errorcode" type="xsd:string" />     <xsd:attribute name="errormessage" type="xsd:string" /> </xsd:complextype> 

then generate

<unassignedsecurityroleusers errorcode="" errormessage="">   <username></username> </unassignedsecurityroleusers>   

how can generate using xsd

<unassignedsecurityroleusers>     <username errorcode= "1" errormessage="">?</username>     <username errorcode= "1" errormessage="">?</username>     ....     .... </unassignedsecurityroleusers> 

thanks

if give username element type="xsd:string" can't have attributes. allow both text content and attributes need give element complextype simplecontent extends xsd:string, , declare attributes on type rather on unassignedsecurityroleusers type:

<xsd:element name="unassignedsecurityroleusers" type="unassignedsecurityroleusers"/>  <xsd:complextype name="unassignedsecurityroleusers">   <xsd:sequence>       <xsd:element name="username" minoccurs="1" maxoccurs="unbounded">       <xsd:complextype>         <xsd:simplecontent>           <xsd:extension base="xs:string">             <xsd:attribute name="errorcode" type="xsd:string" />             <xsd:attribute name="errormessage" type="xsd:string" />           </xsd:extension>         </xsd:simplecontent>       </xsd:complextype>     </xsd:element>   </xsd:sequence>  </xsd:complextype> 

if want able declare other elements same attributes use named complextype instead of nesting inside username element:

<xsd:complextype name="valuewitherror">   <xsd:simplecontent>     <xsd:extension base="xs:string">       <xsd:attribute name="errorcode" type="xsd:string" />       <xsd:attribute name="errormessage" type="xsd:string" />     </xsd:extension>   </xsd:simplecontent> </xsd:complextype>  <xsd:complextype name="unassignedsecurityroleusers">   <xsd:sequence>       <xsd:element name="username" minoccurs="1" maxoccurs="unbounded"                  type="valuewitherror"/>   </xsd:sequence> </xsd:complextype>
