[lxml-dev] XSD Validation: No matching global declaration.

[John Lovell]

Hi All:
 
I don't know if my schema is invalid or if this represents a bug in lxml
or libxml2.
 
Here is the situation...
 
I have a XML Schema that looks like this:
 
<schema 
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:sif="http://www.sifinfo.org/infrastructure/1.x"
targetNamespace="http://www.sifinfo.org/infrastructure/1.x">
 
 <import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="http://www.w3.org/2001/xml.xsd"/> 
 
...
 
 <element name="Authentication">
  <complexType>
   <sequence>
    <element ref="sif:AuthenticationInfo" minOccurs="0"
maxOccurs="unbounded"/>
    <element ref="sif:SIF_ExtendedElements" minOccurs="0"
maxOccurs="1"/>
   </sequence>
   <attribute name="RefId" type="sif:RefIdType" use="required"/>
   <attribute name="SifRefId" type="sif:RefIdType" use="required"/>
   <attribute name="SifRefIdType" use="required">
    <simpleType>
     <restriction base="string">
      <enumeration value="StudentPersonal"/>
      <enumeration value="StaffPersonal"/>
      <enumeration value="StudentContact"/>
      <enumeration value="EmployeePersonal"/>
     </restriction>
    </simpleType>
   </attribute>
  </complexType>
 </element>
 
...
 
</schema>
 
I am trying to validate this data:
 
<?xml version="1.0"?>
<Authentication xmlns:ns3="http://www.w3.org/2001/XMLSchema"
ns3:RefId="27D1CAEA85C2BAA647A01B551D21E1EB"
ns3:SifRefId="211242238C60A55E25B2B86BB337C244"
ns3:SifRefIdType="EmployeePersonal">
  <AuthenticationInfo>
    <System xmlns:ns0="http://www.w3.org/2001/XMLSchema"
ns0:Type="Application">&amp;amp;1&amp;lt;tNk44}F2</System>
    <Username>;pl}ee&amp;apos;-</Username>
    <DistinguishedName>mlZm at JD</DistinguishedName>
    <Password xmlns:ns1="http://www.w3.org/2001/XMLSchema"
ns1:Algorithm="MD5" ns1:KeyName="(v4kSY.">l1uqg!</Password>
  </AuthenticationInfo>
  <SIF_ExtendedElements>
    <SIF_ExtendedElement xmlns:ns2="http://www.w3.org/2001/XMLSchema"
ns2:Name="%~T=">ZE72n/l</SIF_ExtendedElement>
  </SIF_ExtendedElements>
</Authentication>
 
The error log shows the following error:
 
../1.5r1/XSD/Infrastructure/Authentication__Authentication.xml:2:ERROR:S
CHEMASV:SCHEMAV_CVC_ELT_1: Element 'Authentication': No matching global
declaration available for the validation root.
 
The same code given diffrent files works fine.  Does anyone have any
ideas why I am getting this message?
 
Required version information:
 
lxml.etree:        (1, 3, 4, 0)
libxml used:       (2, 6, 30)
libxml compiled:   (2, 6, 30)
libxslt used:      (1, 1, 21)
libxslt compiled:  (1, 1, 22)
 
Thanks,
