Thanks for the report.
The problem appears to be that the root element, regardless of what it is, doesn't get a namespace. This could be fixed in the code generation by adding an XMLName field. In your example, we'd generate something like
type SignatureType struct {
XMLName xml.Name `xml:"http://www.w3.org/2000/09/xmldsig# Signature"`
SignedInfo *SignedInfoType `xml:"http://www.w3.org/2000/09/xmldsig# SignedInfo"`
SignatureValue *SignatureValueType `xml:"http://www.w3.org/2000/09/xmldsig# SignatureValue"`
KeyInfo *KeyInfoType `xml:"http://www.w3.org/2000/09/xmldsig# KeyInfo,omitempty"`
Object []ObjectType `xml:"http://www.w3.org/2000/09/xmldsig# Object,omitempty"`
Id string `xml:"Id,attr,omitempty"`
}
from go-xml.

Actually, looking at this closer, the fact that the Signature field in MetaDataType does not have a namespace seems like a bug.
I recall a previous issue where the code failed to preserve namespaces when importing types across namespace boundaries (as your schema does), but I thought I fixed that. The fact that this schema does not declare a targetNamespace may be relevant -- can you try adding a targetNamespace declaration (the value doesn't matter) to the schema element and try codegen again?

Thanks for the fast respone.
So I changed the schema to
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
xmlns:ex="urn:example"
targetNamespace="urn:example"
elementFormDefault="qualified">
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#"
schemaLocation="xmldsig-core-schema.xsd" />
<xs:element name="MetaData" type="ex:MetaDataType" />
<xs:complexType name="MetaDataType">
<xs:sequence>
<xs:element ref="ds:Signature"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
and adjusted the namespace flag to
xsdgen -pkg=main -o=xsd/test.go -ns "urn:example" xsd/test.xsd xsd/xmldsig-core-schema.xsd
and in this case it seems to use the target namespace but in my case I would expect that Signautre would have the namespace of xmldsig?
type MetaDataType struct {
Signature *SignatureType `xml:"urn:example Signature"`
}
type SignatureType struct {
SignedInfo *SignedInfoType `xml:"http://www.w3.org/2000/09/xmldsig# SignedInfo"`
SignatureValue *SignatureValueType `xml:"http://www.w3.org/2000/09/xmldsig# SignatureValue"`
KeyInfo *KeyInfoType `xml:"http://www.w3.org/2000/09/xmldsig# KeyInfo,omitempty"`
Object []ObjectType `xml:"http://www.w3.org/2000/09/xmldsig# Object,omitempty"`
Id string `xml:"Id,attr,omitempty"`
}
the xml output is now
<Signature xmlns="urn:example">
Did I do something wrong? I am not sure if this was what you thought about.
I am not really an expert in XSD schemas... sorry.
What I forgot to mention is that I am using the omitempty-structs branch but I merged the latest master into it. I also tried it with the master with the same result.

It looks like setting the targetNamespace did not fix the issue and this is a variation of #65 ; elements in another namespace mistakenly get labelled with the targetNamespace of the schema containing the reference.
