-------------------------------------------

Dmitry, 

Could you possibly post an actual patch? I know this is trivial and I'll do it by hand if you really don't want to.

>                 Key: XMLSCHEMA-13
>                 URL: https://issues.apache.org/jira/browse/XMLSCHEMA-13
>             Project: XmlSchema
>          Issue Type: Bug
>    Affects Versions: XmlSchema 2.0
>            Reporter: Dmitry Repchevsky
>   Original Estimate: 1m
>  Remaining Estimate: 1m
>
> The method uses toString() without checking whether namespace exists for the prefix
> public String getNamespaceURI(String prefix) {
>     return get(prefix).toString();
> }
> should be:
> public String getNamespaceURI(String prefix) {
>     String namespaceURI = get(prefix);
>     return namespaceURI == null ? null : namespaceURI .toString();
> }
> the latter fix would allow a correct behavior for the next code found in XmlSchemaSerializer:
>             if (ctx != null && ctx.getNamespaceURI(xsdPrefix) != null) {
>                 xsdPrefix = "xsd";
>             }
