> Hi,
> I have a schema that contains a union of two types, one simple type that is defined in the schema itself and a dateTime. See attached file union-schema.xsd.
> First, I read the schema into an XmlSchema
> {code:java}
> XmlSchema schema;
> try (InputStream is = UnionSerialization.class.getResourceAsStream("union-schema.xsd")) {
>  schema = new XmlSchemaCollection().read(new InputSource(is));
> }{code}
>  Next, I ask to serialize it to a Document and print it to standard output:
> {code:java}
> Document schemaDocument = schema.getSchemaDocument();
> System.out.println(asText(schemaDocument));
> {code}
> The XML that is printed to standard out is not a valid XML schema anymore:
> {code:xml}
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://some.uri" attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://some.uri">
>   <xs:element name="DynamicObject">
>     <xs:complexType>
>       <xs:sequence>
>         <xs:element xmlns:q1="http://some.uri" name="DatePicker1" type="myDateTime"/>
>       </xs:sequence>
>     </xs:complexType>
>   </xs:element>
>   <xs:simpleType name="emptyString">
>     <xs:restriction base="xs:string">
>       <xs:length value="0"/>
>     </xs:restriction>
>   </xs:simpleType>
>   <xs:simpleType name="myDateTime">
>     <xs:union memberTypes="q2:emptyString xs:dateTime"/>
>   </xs:simpleType>
> </xs:schema>{code}
> the memberTypes of the union of simpleType myDateTime contains a prefix q2 which is not defined anymore in the document.
> This is also the exact error I get when feeding the document to another XmlSchemaCollection:
> {code:java}
> new XmlSchemaCollection().read(schemaDocument, null);
> {code}
> {noformat}
> Exception in thread "main" java.lang.IllegalStateException: The prefix q2 is not bound.
