BinaryBase64 Schema Validation

[blondebier]

I have written a schema to validate a response from a web service. It works well except I cannot get the BinaryBase64 tag to validate.

Part of the schema goes like this:

<xsd:complexType name="tyDocument">
<xsd:sequence>
<xsd:element name="DocumentType" minOccurs="1" maxOccurs="1" type="xsd:string" />
<xsd:element name="DocumentStatus" minOccurs="1" maxOccurs="1" type="xsd:string" />
<xsd:element name="PDFFILE" minOccurs="0" maxOccurs="1" type="xsd:base64Binary" />
</xsd:sequence>
</xsd:complexType>

Part of the xml that I’m trying to validate goes like this:

<Document>
<DocumentType>PDF</DocumentType>
<DocumentStatus>Document Produced</DocumentStatus>
<PDFFILE xmlns:dt="urn:schemas-microsoft-com:datatypes" dt:dt="bin.base64"></PDFFILE>
</Document>

The error message I get says, “Error: (-2147467259) The attribute '{urn:schemas-microsoft-com:datatypes}dt' on this element is not defined in the DTD/Schema.
at line 41, column 79”

Any idea how I get it to validate this XML? The problem is that the attribute in the XML cannot change. It has to be: xmlns:dt="urn:schemas-microsoft-com:datatypes" dt:dt="bin.base64"

Can I add this attribute to the schema easily so that it will validate it?

I’d appreciate any pointers.

Cheers,
Francis
