Namespace could not be referenced in the schema

[former_member203641]

Hi,

I am having the xsd in which I am creating some elements which are being referenced from their definition while in the Microsoft Visual Administration tool editor I could see that it gives message that Namespace could not be referenced while I have defined the element type  in the same xsd

e.g.

namespace definition

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:h="http://www.w3.org/1999/xhtml" xmlns:gen="http://www.abc/isd/General" targetNamespace="http://www.abc.uk/isd/General" elementFormDefault="qualified" attributeFormDefault="unqualified" version="2.10" id="general">

definition

<xsd:simpleType name="LEGAL_STATUS_TYPE">

<xsd:union>

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:enumeration value="Formal"/>

     <xsd:enumeration value="Informal"/>

    </xsd:restriction>

   </xsd:simpleType>

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:minLength value="1"/>

     <xsd:maxLength value="35"/>

    </xsd:restriction>

   </xsd:simpleType>

  </xsd:union>

</xsd:simpleType>

declaration

<xsd:element name="LegalStatus" type="gen:LEGAL_STATUS_TYPE" minOccurs="0" maxOccurs="unbounded"/>

Any idea why this problem is occurring?

Thanks,

Amit

Hello Amit,

Instead of

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:h="http://www.w3.org/1999/xhtml" xmlns:gen="http://www.abc/isd/General" targetNamespace="http://www.abc.uk/isd/General" elementFormDefault="qualified" attributeFormDefault="unqualified" version="2.10" id="general">

Try using

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:h="http://www.w3.org/1999/xhtml" xmlns:gen="http://www.abc/isd/General" 
xmlns="http://www.abc.uk/isd/General" targetNamespace="http://www.abc.uk/isd/General" elementFormDefault="qualified" attributeFormDefault="unqualified" version="2.10" id="general">

A target namespace still needs an xmlns declaration without a prefix.

Hope this helps,
Mark

Mark,

Even xmlns declaration is there in the xsd document header but it did not get copied in my post I guess.

I would explain you the exact thing which I am doing..

I have a xsd which has unions and choice tags which PI does not support so I changed the unions to complexTypes with enumerations as AllowedValues element and length restrictions as FreeValue element.

e.g. for above case I changed it to

<xsd:element name="LEGAL_STATUS_TYPE">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="AllowedValues" minOccurs="0">

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:enumeration value="Formal"/>

     <xsd:enumeration value="Informal"/>

    </xsd:restriction>

   </xsd:simpleType>

</xsd:element>

<xsd:element>

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:minLength value="1"/>

     <xsd:maxLength value="35"/>

    </xsd:restriction>

   </xsd:simpleType>

</xsd:element>

  </xsd:sequence>

</xsd:complexType>

</xsd:element>

As soon as I do this the xsd document now gives error that type LEGAL_STATUS_TYPE is not declared.

Thanks,

Amit

Hello Amit,

Since xsd:union is not supported, the best you can do is to retain the simpleType and then combine the restrictions (as long as it is only one type) e.g:

<xsd:simpleType name="LEGAL_STATUS_TYPE"> 
     <xsd:restriction base="xsd:string"> 
          <xsd:enumeration value="Formal"/>  
          <xsd:enumeration value="Informal"/>
          <xsd:minLength value="1"/> 
          <xsd:maxLength value="35"/>
     </xsd:restriction> 
</xsd:simpleType>

As for xsd:choice, it will appear as 0..1 so no problems with that.

Hope this helps,

Mark

All,

Solved my problem. I was referring to element by changing simpleType to element so as to avoid union which is not supported in proxies.

e.g. following was the original xsd and its reference.

<xsd:simpleType name="LEGAL_STATUS_TYPE">

<xsd:union>

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:enumeration value="Formal"/>

     <xsd:enumeration value="Informal"/>

    </xsd:restriction>

   </xsd:simpleType>

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:minLength value="1"/>

     <xsd:maxLength value="35"/>

    </xsd:restriction>

   </xsd:simpleType>

  </xsd:union>

</xsd:simpleType>

<xsd:element name="LegalStatus" type="gen:LEGAL_STATUS_TYPE" minOccurs="0" maxOccurs="unbounded"/>

To avoid unions from xsd I was changing LEGAL_STATUS_TYPE to element from a simpleType as shown below

<xsd:element name="LEGAL_STATUS_TYPE">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="AllowedValues" minOccurs="0">

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:enumeration value="Formal"/>

     <xsd:enumeration value="Informal"/>

    </xsd:restriction>

   </xsd:simpleType>

</xsd:element>

<xsd:element>

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:minLength value="1"/>

     <xsd:maxLength value="35"/>

    </xsd:restriction>

   </xsd:simpleType>

</xsd:element>

  </xsd:sequence>

</xsd:complexType>

</xsd:element>

Since element cannot be type referred so below line in xsd was giving me the error that namespace could not be referred.

<xsd:element name="LegalStatus" type="gen:LEGAL_STATUS_TYPE" minOccurs="0" maxOccurs="unbounded"/>

Solved it by again declaring it as complexType like below instead of element and problem was solved

<xsd:complexType name="LEGAL_STATUS_TYPE">

<xsd:sequence>

<xsd:element name="AllowedValues" minOccurs="0">

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:enumeration value="Formal"/>

     <xsd:enumeration value="Informal"/>

    </xsd:restriction>

   </xsd:simpleType>

</xsd:element>

<xsd:element name="FreeValues" minOccurs="0">

   <xsd:simpleType>

    <xsd:restriction base="xsd:string">

     <xsd:minLength value="1"/>

     <xsd:maxLength value="35"/>

    </xsd:restriction>

   </xsd:simpleType>

</xsd:element>

  </xsd:sequence>

</xsd:complexType>

Reply from Mark was helpful but unfortunately saw that after I implemented it same way .

Thanks,

Amit

I see gen is the namespace prefix given in the declaration.  So it could not find it. In your targetnamespace specify xmlns:gen as prefix... This would solve your problem. Also use xmlspy or online schema validator for validation.

refer this link for doing this

Baskar,

Can you tell me exactly what do you mean by specifying it in target namespace?

because it is already there in the tag <xsd:schema>

Thanks,

Amit
